Hi, Following Sune's answer, I got a rudimentary backtrace. It seems to me that kde daemon is crashing every first time i open amarok.
Can anyone suggest against which packet i should file the bug? Also, the crash handler reports that the backtrace is uncomplete and of little use. Can anyone suggest which other debugging packages i could use? Following is a reduced version of the backtrace. Thanks a lot, j Application: KDE Daemon (kdeinit4), signal: Aborted Using host libthread_db library "/lib/i386-linux-gnu/i686/cmov/libthread_db.so.1".
