Gnome-display-properties crashes if you try to mirror with a smaller screen

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please try to obtain a backtrace following the instructions at http://wiki.ubuntu.com/DebuggingProgramCrash and upload the backtrace (as an attachment) to the bug report. This will greatly help us in tracking down your problem.

Also, please don't put the release name (ie, "karmic alpha 4") in the bug title. It implies that it only happens in that release, which would not be true if it is not fixed by the next alpha.

Hello Chris,

I will do that but I didn't find the dbg package, I was unaware of the ddeb repository.

On a side note, I think I disagree with your use of "incomplete" in Launchpad. For me, it means that it's a bug that cannot even be verified without the requested information.

In this case, anybody with two screens should be able to reproduce this bug, I think I provided enough information to reproduce the bug. Marking it as incomplete is dangerous because if I don't reply, the bug will disapear from LP but not magically from Ubuntu.

Of course, if you tested it yourself with 2 screens and nobody else was able to reproduce that bug, then it makes sense. ;-)

PS : I will do the debugging stuff ASAP, don't worry

No, incomplete means it is still waiting on information to be useful - ie, a backtrace. I don't have 2 screens, and lots of other developers don't either. Without a backtrace, there's not enough information here to do anything.

And also, you assume that everyone else can reproduce the bug - that's not always the case with some crashers. It could just be something unique to your setup (and lots of users have 2 screens and never hace this problem).

I don't know why you think Incomplete is dangerous. It just means that the bug report doesn't have enough information. Bug reports set to Incomplete don't just magically disappear from Launchpad.

Chris > Never mind, it's just that I don't use "incomplete" that way for my projects. Not a big deal, I was just noting it.

In order to be forgiven, I offer you a nice traceback ;-)

Thanks, but there are some debug symbols missing from your trace. Could you please try again with the following extra packages installed:

libgtk2.0-dbg, libglib2.0-dbg, libc6-dbg

Thanks

hope it's complete

Here you have an strace of this problem...

Thanks, I will build a version of gnome-control-center in my PPA later which will print out some debug statements to provide some more information, before I send this upstream.

We have a distro-patch which touches some of this code, so this crash could be caused by that. I will investigate this some more before deciding if it should go upstream.

Ok, this is actually an upstream issue, reported here: http://bugzilla.gnome.org/show_bug.cgi?id=593866
