Sentry Crash Report:

Description Balakrishnan Nair 2009-07-18 06:07:16 UTC 
Application that crashed: amarok
Version of the application: 2.1.1
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-14-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Running Amarok 2.1 on Gnome 2.26.0, on Ubuntu 9.04 64bit(using Kubuntu backports repository to run KDE 4.2.96)

While playing tracks with Amarok, I paused the track for a few minutes, upon returning to the PC and resuming playback, I noticed some of the tracks' album art was missing, and one track had been assigned the wrong artist, where previously it had all been displayed correctly. 'Update collection' had no effect. Upon manually making the corrections Amarok crashed when I tried to 'assign custom cover'.

Now Amarok rescans the Collection folder on each restart, again shows up with missing track info(like artist, album, album art), and crashes each time I try to assign custom cover.

I'm also using the Gnome Multimedia Keys Amarok script(ver 2.0), which goes into Zombie state using up ~20% CPU and persists even after Amarok crashes. Not sure if that has anything to do with it.

Sorry, but your backtrace lacks quite some debugging symbols. If you can reproduce this crash, please see here on how to reproduce a valid backtrace:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

On Ubuntu, you need to install the amarok-dbg files at least. Ideally you should install all debugging packages for the applications you are running.
Comment 2 Balakrishnan Nair 2009-07-18 16:18:08 UTC 
After filing this bug report, I uninstalled Amarok 2 and dependencies(including configuration files), and installed Amarok 1.4(using a Launchpad PPA https://launchpad.net/~bogdanb/+archive/ppa ) since Amarok 2 had become pretty much unusable with the collection full of errors. It would keep updating the collection database and new errors kept popping up. Reinstalling Amarok 2 or manually rescanning the collection didn't seem to make any difference. 
So I just switched to Amarok 1.4 and rescanned the collection(SQLite).

It was only then that I saw Myriam Schweingruber's  comment here. So I then uninstalled 1.4 and reinstalled Amarok 2 and the dbg package(~180 MB).
The entire collection at ~/Music was rescanned, and library info now shows correctly including album art.

The trouble is, I no longer get the crash when assigning custom covers, and can't reproduce the bug. I've tried all the stuff I was doing when the trouble started, but so far Amarok has remained frustratingly stable. Everything seems OK, including the Gnome Multimedia Keys plugin.

Since the bug seems to have been marked Resolved (in Amarok 2.2) here 
https://bugs.kde.org/show_bug.cgi?id=200249

I'm going to hope for the best and stick with things as they are for now and not mess up my current set-up. I'll update this with as much debugging info as possible if this happens again(fingers crossed).

Regards to all and many thanks.
Comment 3 Myriam Schweingruber 2009-07-18 16:34:39 UTC 
You are welcome, thanks for your report and feedback. Marking as solved then (duplicate of 200249). Feel free to reopen if you should come across this again once Amarok 2.2. is released.
