Description Andreas.Feldmann 2009-06-22 21:26:39 UTC

Version:           2.1 (using KDE 4.2.4)
OS:                Linux
Installed from:    Ubuntu Packages

I installed Amarok 2.1mysql5.1.30-0ubuntu2~jaunty2_i386 from the backports repos in Ubuntu Jaunty. When I start Amarok I get the splash screen but after that it crashes with a signal 11 and I get the following backtrace:

Application: Amarok (amarok), signal SIGSEGV

I hope this helps since I would really really like to have Amarok 2.1 running on my system...

Comment 2 Myriam Schweingruber 2009-06-23 11:59:53 UTC

Alexey: no, not the same bug.
Andreas, does it crash every time you start Amarok 2.1? Try removing your database located in ~/.kde/share/apps/amarok/mysqle/ (that folder) and start again. You might have a crash on the first start, but the next start should be running (another bug, solved in 2.2.-SVN)

Comment 3 Andreas.Feldmann 2009-06-23 20:40:07 UTC

Hi,
and thanks for the quick reactions first of all. I really appreciate it. 
@Alexey: Amarok crashes every time. I have never seen the 2.1 window :( . Unfortunately Amarok will still crash after removing the mysqle directory. Also after several restarts.

I installed some more dbg packages which produced the following output (after moving the mysqle directory back to where it belongs):

actually I meant @Myriam...

Comment 5 Myriam Schweingruber 2009-06-24 13:02:39 UTC

Andreas, this looks very much like a Phonon installation problem. You should try forcing a reinstall of phonon and the phonon-xine-backend. Something went wrong in your system installation. For more help on this, please join the #kubuntu channel on irc.freenode.net

Comment 6 Myriam Schweingruber 2009-06-24 13:07:14 UTC

Andreas, sorry to bother again, but the result of 

export PHONON_XINE_DEBUG=1; amarok --nofork

would be nice to have, too :)

Comment 7 Andreas.Feldmann 2009-06-24 19:39:54 UTC

Don't worry about bothering me :)
reinstalling all packets that carry phonon in their name gives the same behaviour of Amarok as before.
export PHONON_XINE_DEBUG=1; amarok --nofork gives the following output:
