Version: 3.4.1 (using KDE 3.4.1, Gentoo) Compiler: gcc version 3.3.5-20050130 (Gentoo Linux 3.3.5.20050130-r1, ssp-3.3.5.20050130-1, pie-8.7.7.1) OS: Linux (i686) release 2.6.11-gentoo-r11 Steps to reproduce: 1. Go to http://www.sonyclassics.com/savingface/ 2. Open the 'View Trailer' link 3. Close both windows, in any order. 4. Crash This might be related to the Kaffeine, as that is the mediaplayer I use. I'll also supply a less usefull backtrace (almost no debug symbols) from KDE 3.3.2 on Debian in a moment. Window closing order does not seem to affect the backtrace (other than the LWP numbers being different, as expected). The backtrace: Using host libthread_db library "/lib/libthread_db.so.1". `system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.

Created attachment 11921 [details] Valgrind log of konqueror / kaffeine crash After some further searches I found that this error has been reported several times already, and is supposedly a Kaffeine bug. Comment 1 in Bug 99586 seems to suggest that this might be a problem with Konqueror making pointer errors. So I put it through valgrind (log is attached). The endless repeating output from thread 7719 is probably the Xine thread writing to the screen. When that appeared I hit the X button. Konqueror ran until the first frames of the video appeared on the screen, and then exited. My system is still recompiling itself with -ggdb3, so the interesting part within Xine/Kaffeine might be the part that says "by 0x1DECF6BF: ???".. I had to kill valgrind at the end, it didn't exit by itself (waited a long time) :-/ Output from the commandline follows.: henk@MFL ~ $ valgrind --error-limit=no --log-file=KonquerorKaffeinePlugin.log konqueror http://www.sonyclassics.com/savingface/trailer300k.html External func OLEAUT32.dll:8 DMO dll supports VO Optimizations 0 1 DMO dll might use previous sample when requested GetOutput r=0x0 size:230400 align:1 StreamCount r=0x0 1 1 Decoder supports the following YUV formats: YV12 YUY2 UYVY YVYU ▒ Decoder is capable of YUV output (flags 0x1b) Total Unfree 60 bytes cnt 1 [(nil),0] Killed
Created attachment 11923 [details] Valgrind trace with --num-callers=50 A suggestion from dfaur at #khtml on irc.debian.org. Now I should go and push the kaffeine devs to look the relevant backtraces littered over this bugzilla.
