Application: dragon (2.0) KDE Platform Version: 4.4.2 (KDE 4.4.2) Qt Version: 4.6.2 Operating System: Linux 2.6.32-22-generic i686 Distribution: Ubuntu 10.04 LTS -- Information about the crash: I opened a few-second long .avi clip (i can provide it upon request). The automatic resizing of the player's window shows about a quarter of the actual clip, say quadrant from 9h to 12h. Then the application crashes unexpectedly. The behaviour is perfectly reproducible. Unfortunately i don't have clips of other format to see if they crash, too. This happened on a Kubuntu Lucid machine with all the official updates installed. The crash can be reproduced every time. -- Backtrace: Application: Dragon Player (dragon), signal: Segmentation fault [Current thread is 1 (Thread 0xb7814710 (LWP 4487))] Thread 9 (Thread 0xb605db70 (LWP 4490)): #0 0x00834422 in __kernel_vsyscall () #1 0x00738342 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x03b9aa34 in pthread_cond_timedwait () from /lib/tls/i686/cmov/libc.so.6 #3 0x003f5ce7 in ??

Update: After reporting the bug i watched the same exact video on Dolphin previewer and it worked fine.
can you consistently reproduce this, even with the latest Qt?
Unfortunately right now i'm away from my computer and therefore i can't answer your question. i shall be back in about a week and look into it. regarsds, j On 29/06/2010, Martin Sandsmark <sandsmark@samfundet.no> wrote: > https://bugs.kde.org/show_bug.cgi?id=241654 > > > Martin Sandsmark <sandsmark@samfundet.no> changed: > > What |Removed |Added > ---------------------------------------------------------------------------- > Status|UNCONFIRMED |NEEDSINFO > CC| |sandsmark@samfundet.no > Resolution| |WAITINGFORINFO > > > > > --- Comment #2 from Martin Sandsmark <sandsmark samfundet no> 2010-06-29 > 21:54:27 --- > can you consistently reproduce this, even with the latest Qt? > > -- > Configure bugmail: https://bugs.kde.org/userprefs.cgi?tab=email > ------- You are receiving this mail because: ------- > You reported the bug. >
Hi there, I updated my system by adding to the sources ppa:kubuntu-ppa and running a safe-upgrade. Here is my new configuration Application: dragon (2.0) KDE Platform Version: 4.4.5 (KDE 4.4.5) Qt Version: 4.6.3 Operating System: Linux 2.6.32-23-generic i686 Distribution: Ubuntu 10.04 LTS There are some improvements: the video is now fully played and there are no more weird artefacts when the window self-resizes. The program now crashes when, at the end of the playback, I click on either the play button to play again or the close button on the title bar to close the window. Unfortunately the KDE crash handler was unable to find the debugging packages, therefore the following backtrace will serve very little help, I'm afraid. I send it nevertheless, and if anyone wants to send me a few instructions on where to find the dbg packages, I shall be glad to help. Thank you and best regards, Jacopo Application: Dragon Player (dragon), signal: Segmentation fault [Current thread is 1 (Thread 0xb7848710 (LWP 1754))] Thread 9 (Thread 0xb6014b70 (LWP 1755)): #0 0x00126422 in __kernel_vsyscall () #1 0x02a64342 in pthread_cond_timedwait@@GLIBC_2.3.2 () from /lib/tls/i686/cmov/libpthread.so.0 #2 0x01c05a34 in pthread_cond_timedwait () from /lib/tls/i686/cmov/libc.so.6 #3 0x0018bce7 in ??
