Application: gwenview (2.8.4) KDE Platform Version: 4.8.4 (4.8.4) "release 6" Qt Version: 4.8.2 Operating System: Linux 3.4.2-28-desktop x86_64 Distribution: "openSUSE 12.1 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: I viewed an image with Gwenview and wanted to open it with Gimp by selecting the "Open with" option in the context menu that comes up when pressing the right mouse button. The menu works fine but as soon as I move the mouse over the "Open with" entry, instead of opening a sub-menu, Gwenview crashes. I installed the newest KDE4 packages from the OpenSuse Tumbleweed repositories. The crash can be reproduced every time. -- Backtrace: Application: Gwenview (gwenview), signal: Segmentation fault [Current thread is 1 (Thread 0x7f0b89523760 (LWP 7906))] Thread 3 (Thread 0x7f0b75e9a700 (LWP 7910)): #0 0x00007f0b85eb9ff3 in poll () from /lib64/libc.so.6 #1 0x00007f0b822c9ae8 in ??

I can't reproduce this in Gwenview 2.9.0.
(In reply to comment #1) > I can't reproduce this in Gwenview 2.9.0. Where can I get Gwenview 2.9.0? It doesn't seem to be available anywhere on the OpenSuse build service nor the official KDE source tree at http://download.kde.org
Gwenview 2.9.0 is part of KDE 4.9 beta2.
(In reply to comment #3) > Gwenview 2.9.0 is part of KDE 4.9 beta2. That's what I suspected. Given that KDE 4.9 won't be out for a while and that the next OpenSuse release 12.2 will still use KDE 4.8 it would be good to have this bug fixed in the KDE 4.8 version of Gwenview as well. It shouldn't require much, from what I can gather from the crash dump it may be to do with identifying the MIME type, but I may well be on a completely wrong track there.
After doing some more research into this, I think there is a more general problem with KDE 4.8.4 in combination with Soprano 2.7.6 which come together in the OpenSuse repositories. See this thread on the kde-core devel mailing list: http://lists.kde.org/?t=133931393100003&r=1&w=2

For the records: as described in the kde-core devel mailing list I have linked to above, replacing Soprano 2.7.6 with version 2.7.56 (also now in the OpenSuse Tumbleweed repository) will fix the problem. The issue seems to be an incoherent change to socket handling in KDE 4.8.4, in particular the socket at /tmp/ksocket-${USER}/nepomuk-socket which is accessed by Gwenview.
