Segmentation Fault (crashes) when I try to move a large pattern

please try a new build after rev 20874

Little bump, please keep us informed.

Another similar bug (409901) has been solved meanwhile. Could the reporter try a newer release to see if it's solved?

Happening to me in Xubuntu 9.04 32-bit with version 0.46. Any imported pattern I try to drag, scale, or rotate causes a segmentation fault (though I'm always using very large patterns, over 1600x1200 pixels). The built-in patterns do not.

What's very strange is I can apply a pattern, then try to move/scale it, and Inkscape will crash. Then I start it again and this time I can do it just fine, once. If I do it a second time, it will crash again. So with enough patience it's possible to use large patterns, just quite annoying...

Attached backtrace shows me importing an object, converting it to a pattern, deleting the image it leaves behind, applying it as a fill to a layer, and trying to scale it. Notice I do this successfully once, close normally (without saving), then do it again, and this time it breaks.

could you try a more recent version, available from :
http://sourceforge.net/projects/inkscape/files/

Appears to work in 0.47. Though the cursor does tend to "drop" the handles; i.e. when I click and drag the scale handle, it only drags a few pixels, then I have to release and drag again to move it the rest of the way. Seems as though it's not polling the mouse under the heavy CPU load it has when it begins scaling, and then sees that the cursor has moved so far and assumes I've let go of the button. Only a minor annoyance.

Correction: not fixed, just can't reproduce reliably anymore. Just happened again.

same problem here with a freshly built 0.47 from svn, it happens even with small patterns

happens with small images too, but only on paths, if i apply a pattern to e.g. a rectangle object, it works fine, and i can move, rotate etc. the pattern. Trying the same thing with paths freezes the system.

I can confirm it on ubuntu 8.04_64 (svn build) and on ubuntu 9.10_x86 (official ubuntu package)

the problem is triggered by any custom pattern on my system, both bitmap and vector based, whenever you try to adjust a pattern scale, position or orientation applied to a path using the node tool.
Built-in patterns are ok, and objects (rectangles, circles, etc.) with custom patterns applied are ok as well, if converted to paths the crash occurs again

If i try to run gdb, only thing I get is:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7f15d74c07c0 (LWP 25018)]
0x0000000000756263 in SPObject::requestDisplayUpdate ()

then the whole Gnome freezes and I have to switch to a text terminal to kill gdb or inkscape instance

Same crash in 0.47 release version. I tried last trunk version (rev. 9172) - problem solved.

Could an affected user attach a file which crashes 0.47, so that we can confirm this bug and the fact that it's now fixed?
I've tried to reproduce this issue many times, but never managed to crash inkscape...
Thanks!

Inkscape crashes at first movement of node; or it crashes or freezes at several movements.

@Denis - your issue looks like bug #463602 “crash when node-editing pattern-filled object” which was recently fixed in bzr trunk. AFAIU this report is less about using stock patterns but about (big) custom (bitmap) patterns.

Oh, yes. I think this bug (#271723) is exactly same as bug #463602.

> I think this bug (#271723) is exactly same as bug #463602.

No, I don't think so - at least is has not been confirmed as such. Please read the original bug report here (bug #271723) and earlier comments which explicitly state «Any imported pattern I try to drag, scale, or rotate causes a segmentation fault (though I'm always using very large patterns, over 1600x1200 pixels). The built-in patterns do not.» and another «Built-in patterns are ok»

The example you attached however uses the built-in 'Stripes' pattern and looks like the issue reported in bug #463602 (which is marked as fixed in bzr trunk).

OK.
I performed test for clarity. System: Ubuntu 9.10, kernel 2.6.31-20-generic, GNOME 2.28.1
Inkscape 0.47 release version:
Built-in pattern - app crashes.
Small bitmap pattern (38KB, 640x519) - app crashes.
Medium bitmap pattern (433KB, 1920x1200) - app crashes. # see attachment (try several movements of nodes)
Big bitmap pattern (3.2MB, 3264x2448) - app freezes.

In last bzr version everything work as expected.

Sorry. Forgot to embed image in previous post.

Strange. While I sometimes manage to reproduce the crash in 0.47 with 'crashtest.svg' from comment #14 I failed so when trying with medium_pattern.svg (tested with Inkscape 0.47 r22583 and 0.47+devel r9172 on OS X 10.5.8 with both default and custom preferences).

I can't confirm that this bug exists in 0.47, is the same as bug #463602 and/or is fixed in 0.47+devel from bzr trunk.
@JazzyNico - any success on your side to reproduce the crash?

I've just reproduced Denis' bug on Ubuntu 9.10, Inkscape 0.47 (not with the dev version) with medium_pattern.svg (default preferences).
But it freeze when moving the shape's nodes, not the pattern's ones. Thus I think Denis' bug is the same as bug #463602, but not the same as the original report.
Backtrace attached.

But I'm not 100% certain. The backtraces look somewhat different.

@DannyKing, do you still have this bug? If so, could you please attach an example file so that we can test and compare with the one provided by Denis?
Thanks!

JazzyNico, you are right. It is my inattention with bug description. I moved nodes of path but not pattern itself. I apologize for misleading.

Closing this bug report as the original bug could not be reliably repeated and no further information from affected users received.
If the problem reappears, feel free to revert the bug status.
