Description PC LX 2009-11-04 02:47:41 UTC 
Application that crashed: okular
Version of the application: 0.9.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-desktop-1mnb x86_64
Distribution: "Mandriva Linux 2010.0"

What I was doing when the application crashed:
This crash always happens if I do the following:
1 - Try to load a particular zip file but apparently nothing happens. The GUI remains unchanged and no images are shown as normally would happen.
2 - Try to load the same zip file a second time a message saying that "Não foi possível abrir o file:///tmp/file.zip" (in English "It was not possible to open the file:///tmp/file.zip").
3 - Try to exit Okular but it immediately crashes.

I frequently use Okular to view images inside zip files and the only unusual thing I notice in this particular zip file is that the directory inside has a strange name (probably Japanese). If I rename the directory inside the zip file (and everithing else remains unchanged), Okular shows the images without any problems and there is no crash.

Comment 1 Dario Andres 2009-11-04 03:01:35 UTC 
It seems to be a KFile issue (may be related to the Nepomuk file widget)..
Comment 2 Dario Andres 2009-12-07 00:30:33 UTC 
Old title: Okular crashed when exiting and after trying to load a zip file with images inside a directory with a strange name (japanese probably)

Comment 8 Michael Pyne 2010-01-10 00:06:32 UTC 
The crash seems to be memory corruption (at least for the second backtrace). The this pointer for the KFileAudioPreview is corrupted, and instead looks like a QString.

Converting to ASCII shows these four bytes: "HALE". Not sure what that means though but there's something screwy going on corrupting memory. Perhaps running under valgrind can help diagnose what?
Comment 9 Michael Pyne 2010-01-10 00:08:37 UTC 
Not sure what the conversion would be for the first error'ed this pointer but it looks like ASCII with nulls as well. Also I got the order wrong on the second backtrace, should be ELAH.

Comment 27 Christoph Feck 2010-08-07 23:35:05 UTC 
This bug is believed to be caused by Phonon::PulseSupport starting an local event loop. This has been fixed in Phonon version 4.4.1. For a detailed discussion, see bug 228324.

If you can still reproduce the bug with Phonon version 4.4.1, or on older Phonon version that is not compiled with PulseAudio support, please reopen the bug.

(Interestingly, the initial backtrace in comment #0 and one of the duplicates do NOT have the Phonon::PulseSupport stack entry, but seeing that all other duplicates have it, I doubt these are two separate issues.)
