I can confirm this bug. I have both KDE 3.5.8 and KDE 4.0. It has only happened twice and both during a KDE 4.0 session. I cannot reproduce it, as it seems quite random.

i have reproduced this 5 times today
I am able to reproduce this, happened five times today using KDE 4.0.3 installed from SUSE RPMS. It seems to happen when every a sound should play, an example opening a window, closing a window, logging in. What is where is the system seems to hang for about a minute before the crash handler comes up with details. My system ate the first backtrace that happened when I logged into KDE 4 but I have others: [?1034h(no debugging symbols found) Using host libthread_db library "/lib/libthread_db.so.1".

Maybe this helps: This happend also for me as I've enabled Deinterlacing for Files in the KDE Sound-Settings Dialog. Disabling it brought the Sound back again.
Yes, after enabling Deinterlacing for Files I got a crash quite soon. Application: KNotify (knotify4), signal SIGSEGV Using host libthread_db library "/lib/libthread_db.so.1".

SVN commit 835987 by lunakl: Remove emitting of aboutToQuit() from KApplication::xioErrhandler() - the application is not about to quit, it is about to fall flat on its face. There is really not that much to do once KDE apps lose their connection to the X server. How that can happen while the X server still continues to run is a different question and I don't know the answer. It is quite possible it is caused by careless usage of one X connection from several threads concurrently without proper locking.

Arts is no longer developed and has been unmaintained for quite some time - more than 2 years. With phonon as the replacement for arts in KDE4, we're closing out all the arts bugs in Bugzilla since there is no chance of them being fixed. Thanks

The problem does not occur with other Vorbis users, I can play manually the same files as knotify4 tries by e.g. ogg123 without any problem. Also, I had Pairs crashed the same way. So it's either libvorbis's bug or Phonon GStreamer backend's one.
(In reply to comment #11) > The problem is NOT aRts-specific (did you ever read the whole issue?), and > is still there in 4.10: I don't think that crash is related with this report. Considering that this report against arts is very old and already contains noise, it is better to create a new report against phonon-backend-gstreamer for you crash. It causes more trouble than benefit to reuse such an old report for one unmaintained product.
Got it: https://bugs.kde.org/show_bug.cgi?id=315142 . Thank you for your time.
