Bug 121921

I seem to have the same problem, but I have more information :-)

Description:
------------
In konqueror, I right click on a folder and "open with" gwenview.
Then I do nothing and just close gwenview with the close button of the window.
Which results in a crash.

Used software:
--------------
Distro: OpenSuSE 10.1
Qt: 3.3.5
KDE: 3.5.1 Level "a"
Gwenview: 1.3.1

Tracing:
--------
System configuration startup check disabled.

Thanks for the additional info. A few questions:
- Does it happen on all folders?
- If not, what does the "bad" folder contain?

I created a new empty folder. I can open it with gwenview.
Then I close gwenview -> crash (same bt).
Oh yes, and it always happens. Is this a suse problem?
I did install it from packages (I even think it's in the base-install).

I don't know if it's a SuSE problem or if the problem was fixed with 1.4.0, but I can't reproduce the bug. Can you try to upgrade to 1.4.0?

I use Kubuntu feisty fawn, here with gwenview 1.4.1(KDE 3.5.6)

It crashes on closing, if a video-file had been displayed.
Viewing many images of any format doesn't produce a crash.
But if there was only one video among those image it crashes.

This is the report of one of these crashes

Could it have do do with the video codecs installed on the system?

I use Kubuntu feisty fawn 7.04 with gwenview 1.4.1(KDE 3.5.7) . it crashes just after showing a video when I select anything else. Pity because the program is great! please do something! thanks

I hope this can help:
when showing an image I guess that gwenview uses konqueror and I found out that if I load the same video with konqueror, after it is shown, any other action cause the the konqueror frame to crash causing the signal 11 (SIGSEGV)
please see the following bug report (new)
https://bugs.launchpad.net/ubuntu/+source/kdebase/+bug/47214

hmm, it seems i can reproduce it at least with an mpg i created with kipi-plugins
and my x86_64 arch.
Aurelien can you point me in how videos are loaded please?

We've got it :) as discussed here:
http://thread.gmane.org/gmane.comp.kde.gwenview/1915
gv crashes if libxinepart.so is used as default kpart engine.
switching to kmplayer one worked well instead. So the problem is in kaffeine kpart.

Aniway i made some tests on new kaffeine version and it doesn't crash anymore so it should be fixed now.

For kaffeine developers, i've found a crash though if /dev/dsp is not allowed for user who started it.
[diabolik@cooker ~]$ rpm -qa | grep kaffeine
libkaffeine0-0.8.5-2mdv2008.0
