Description madcatx 2012-06-04 17:39:42 UTC 
Application: amarok (2.5.90)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Amarok crashes when the "Eject" button is clicked while the iPod tracks are being loaded. It does not matter whether the track loading is manually interrupted before clicking the "Eject" button. Similar crash happens when Amarok is closed during the tracks loading.

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Ultrawhoops! I compiled Amarok on another machine where I can install all the debugging symbols and I forgot to apply the "crash on eject" patch (see bug 300958). The patch doesn't have any apparent effect on this crash, I just wanted to make sure I didn't report any bogus info. I attached another crash log which I get with the patch applied. I'm sorry about this...

Please always paste backtraces inline, else those are not searchable.

Git commit aa913a59a047205ed15a7f37f9f11d56785b6ff3 by Matěj Laitl.
Committed on 05/06/2012 at 14:37.
Pushed by laitl into branch 'master'.

IpodCollection: finally safe solution for crash on early eject

We now (asynchronously) wait for the job that parses iPod tracks and
playlists before destroying IpodCollection.

Other change is that we factor playlists parsing into
IpodParseTracksJob, it really belongs there. (previously it was just
called from that thread and it made false impression that the method
is only called from the main thread)
FIXED-IN: 2.6

Applied and tested. Works perfectly on Ubuntu 12.04, but I'm still having some issues on Arch Linux. Those have very likely nothing to do with Amarok, I'll have to look into that a bit more...
