Bug 205528

start 'amarok -d' and post the output. Also install amarok with +debug and get a backtrace.

There's no any difference between starting with "-d" or without.
Here's output:
vooft@vooft ~ $ amarok -d

Maybe i made smth wrong? I've added flag +debug to it's uses, recompile amarok and amarok-utils, but nothing was changed.

you should get the KDE crash dialog when amarok crashes. Maybe you don't have drkonqi installed?
If you do, then use gdb to run amarok. More info on how to get backtraces on gentoo: http://www.gentoo.org/proj/en/qa/backtraces.xml

Yeah, drkonqi was not installed.

Output is here:

Afaik, ipod should be processed by ipodcollection handler, not by mediadevicecollection, but maybe i'm wrong.

you haven't compiled amarok with +debug.
see all the ?? () from /usr/lib64/libamaroklib.so.1

I've added +debug, but some symbols were stripped, sorry :)

Bart will more likely know what's going on there

Looks like you have a completely messed up database there.

Just to test please do this in a terminal:
# cd ~/.kde/share/apps/amarok
# mv msqle mysqle-backup

and start amarok in debug again with:
# amarok --debug --nofork

and don't forget the backtrace if it still craches.

Bart

I moved mysqle directory and started with "--debug --nofork" options.

http://paste.org.ru/?fsaktn -- here's output in console.
http://paste.org.ru/?h4e6b2 -- here's output in crash dialog.

I just noticed that your backtrace has absolutely nothing to do with the ipod you mention in the report. Are you sure this is the same crash and does it only happen with the ipod mounted?

Try a rev after v2.1.1-1678-g5531416 (from just a minute ago) and see if there is any change.

No, it still crashes with ipod mounted and don't crash when ipod is unmounted, but, it seems, in another place.

Here's output and backtrace: http://paste.org.ru/?z8cdw0

Seems like sqlStorage is invalid. But this can normally only happen if your install is seriously fucked up. Nothing should work in this case.

Are you using an external MySql server? If you don't know you didn't because mysqle is the default.

Nikolay, any news on this?

I've recompiled almost everything: Qt, MySQL, libgpod, kdelibs, phonon, xine, amarok - but it still fails only when ipod is attached. Without this one amarok starts fine.
I don't know what to do else.

I really need confirmation of a second user for this. While it's possible this is caused by one singleton being constructed before the other, it might just as well be a messed up setup.

Good day!
I've just rebuild the lastest revision and amarok starts and works fine! 
Thanks for your attention!
