When trying to attach any sort of .png-file kontact crashes. This only happens if file-preview is enabled in the fileselector, which seems to be a good hint, what may cause the crash (anyway.. if a preview is not working, the fileselector should not take the whole app down, or?) backtrace: Kontact (kontact), signal SIGSEGV [Thread debugging using libthread_db enabled] [New Thread 0xb4c948e0 (LWP 5833)] [New Thread 0xaa0e5b90 (LWP 5866)] [New Thread 0xab8abb90 (LWP 5865)] [New Thread 0xac0acb90 (LWP 5864)] [New Thread 0xaca7ab90 (LWP 5863)] [New Thread 0xad664b90 (LWP 5862)] [New Thread 0xade65b90 (LWP 5859)] [New Thread 0xaeaa4b90 (LWP 5858)] [New Thread 0xaf2c6b90 (LWP 5857)] [New Thread 0xafcbdb90 (LWP 5854)] [KCrash handler] #6 0xb00873b8 in yuv444_to_yuy2_mmx () from /usr/lib/libxine.so.1 #7 0x000007fe in ??

Sorry, but the backtrace is useless as it just shows symptoms of another bug which your report doesn't give any info on. The application got an XIO error and handles that by calling exit. That in turn calls the Phonon cleanup routines which crash because of some earlier memory corruption or because of the XIO error, I guess. The real problem is somewhere else. If you can reproduce the crash then you can try to figure out what's causing the XIO error. The first thing to look at is the debug output. As X errors are reported asynchronously they don't show up in the stack trace. AFAIK you can make X calls synchronous though...
