calibre don't launch and eat all ressource

The symptom I get is that when I try to launch Calibre it logs me out (lightdm crashes?). Can you confirm the same? Setting Medium importance as it has a severe impact on a non-core application.

Yeah, now, when I launch calibre I get logged out , but this behavior is
new.
The system doesn't more get frozen, just after a time get out logged.

system frozen after launch of calibre.
no possibility to go on a tty to kill te process, the only thing I can do is to press the power button and the system shutdown normally..

calibre is not present in menu (I launch it from terminal)

Same thing occurs when starting picard. Could it be qt bug or something?

Oneiric, Calibre 0.8.8 from the official Ubuntu repo, same behavior.

I poked around a little and it seems that Calibre sets an impossible size requirement on the WM. xprop returns the following:

[ snip ]
program specified minimum size: 16383 by 16383
program specified size: 16777215 by 16777215

While this is most certainly a *glaring* omission on the part of Metacity and gnome-shell which both crash and/or consume inordinate amounts of memory trying to allocate billions of pixels, Calibre should play nice as well. (Unity was the only WM which actually let Calibre run, giving it an invisible window; that's how I got to xprop it in the first place.)

I have the same issue in Oneiric on an AMD64, but was able to restart after being patient for about 6 minutes.

Hi,

After playing a bit with the upstream 'package' (that include libraries) and the one in Ubuntu, I found that it's a bug in Qt: I'm able to reproduce the issue as soon as I use the system libQtGui.so file.

I found bug #805303 that seems to be the same, and if I use the workaround described there, I've been able to start calibre.

the step I followed are:
- install the qt4-qtconfig package
- run qtconfig-qt4, and set appearance to motif instead of default one

I'll keep this bug report open so that people having the issue can find it.

Thanks,
Fabrice

If you go to the Calibre website and install the latest version (0.8.17) via the terminal you may find as I did that it works beautifully. It's more KDE than Gnome in appearance, but also more familiar to those migrating from Windows.

It also fits the desktop better than it does in Natty.

Hi,

It works because it's bringing with him all required libraries, including the 'buggy' libQtGui (an older version, it seems). This is also why the appearance is not the same as the system, as its not using the parameters used at system level.

The issue with that approach is that:
- those libs may need some security fix that you will never get
- you have to install/uninstall the software by hand
- it's overwriting some files installed by the package
meaning that if you want to install the application from the website, you have to uninstall first the calibre and calibre-bin packages.

Hope this helps,

Fabrice
