Description Matt 2009-09-23 13:17:16 UTC 
Application: amarok (2.2-GIT)
KDE Version: 4.3.68 (KDE 4.3.68 (KDE 4.4 >= 20090916)) (Compiled from sources)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.5 x86_64
Distribution (Platform): Gentoo Packages

What I was doing when the application crashed:
If my iPod is mounted before I start amarok, amarok crashes during splash screen.

If my iPod is not mounted before I start amarok, amarok starts fine. As soon as I mount my iPod, amarok crashes.

Comment 1 Mikko C. 2009-09-23 13:35:18 UTC 
backtrace indicates a crash in libgpod, but it's missing debug symbols:

Comment 2 Matt 2009-09-23 17:03:11 UTC 
This may be a dumb question but how do I rebuild libgpod with debug symbols?
Comment 3 Matt 2009-09-23 17:36:37 UTC 
I recompiled libgpod with -ggdb and didn't strip the binaries.  

I hope this helps.

Comment 4 Mikko C. 2009-09-23 17:42:48 UTC 
I suggest you try asking upstream to libgpod devs, they will know better.
