Version: (using Devel) Installed from: Compiled sources Compiler: gcc 4.3.1 OS: Linux Hi, Applications like juk and amarok (so far, it seems they are the only 2 affected here) crash at startup. Error message: juk(19872): Communication problem with "juk" , it probably crashed. Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" " KCrash: Application 'juk' crashing... sock_file=/home/kde4/.kdemod/socket-cghislai/kdeinit4__0 backtrace: Application: JuK (juk), signal SIGILL (no debugging symbols found) Using host libthread_db library "/lib/libthread_db.so.1".

Anyway, i contacted the guys providing the binaries (kdemod.ath.cx/) and they updated it to recent SVN : $ kded4 -v Qt: 4.4.0 KDE: 4.00.82 (KDE 4.0.82 >= 20080610) KDE Daemon: $Id: kded.cpp 813532 2008-05-27 23:21:49Z dfaure $ The first binaries i tried used the qt phonon; the second one use kde phonon. I tried both phonon backends but the same error come back. I tried compiling DBUS from git as there was a somewhat recent fix about timer (http://gitweb.freedesktop.org/?p=dbus/dbus.git;a=commit;h=cdca6dbce88fd1e1195e2a81eb6619c782df2fac), it didnt work. Restarting DBUS, rebooting, cleaning .kde & co don't work. I'd be glad to help further, but i still have some exams to pass :D Thanks, Charly
Created attachment 25279 [details] amarok's bt console output from amarok, with a better backtrace.
reassigning to Phonon, as it looks like that is where the problem is.
I can confirm this problem with kde compiled from svn trunk. I get this error with amarok, juk and dragonplayer. $dragon setting xine verbosity to 0 KCrash: Application 'dragon' crashing... sock_file=/home/fabrizio/.kde4/socket-fabrizio-desktop/kdeinit4__0
check the dupe for this https://bugs.kde.org/show_bug.cgi?id=167116
The information provided doesn't point to any place in Phonon's code where the bug could be. Also I can't reproduce the crash so I need a better backtrace or valgrind trace.

@Soren Tarp: your crash is unrelated to this. To the original reporter: have you experienced this crash again with a recent KDE version? Thanks
not that I'm the original reporter, but this may be helpful... i COMPLETELY removed amarok from my system (previously had purged with apt-get but wasn't enough), all files and directories that had "amarok" in them at all. I then reinstalled the newer ubuntu,jaunty version 2.0.2 as well as a database-related package it recommended (don't remember what its name was). upon startup it rescanned my music folders and everything has been fine since (1-2 weeks)! - jeremy
@Jeremy: did you experienced the *Same* crash before? (with the same backtrace) ? Thanks
Hi, I'm the original reporter and didn't experience any more of those crashes. The phonon build provided by my distro (arch linux) only provides the xine backend now, by that time i used gstreamer. Sorry for forgetting those old bugs and thank you for the great work! Charly
