Application: amarok (2.4.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-14-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:

Amarok crashes everytime when it starts trying to play music. It doesn't get as far as making any sound, and it doesn't matter whether I press the play button or doubleclick a track, load a playlist or whatever. Source of music also seems irrelevant (local files, or off the web.)

Sound is working on the system. Desktop notifications from kde play okay and ogg123 works at the commandline.

I've just upgraded from Ubuntu maverick to oneiric (all current updates, +1). That, and the stack trace indicates that this is potentially a duplicate of the marked bug, however that is closed as a downstream problem. I've been to the ubuntu bug (LP: #877358), enabled the proposed updates, and installed the fix currently resising in the proposed repo. (at-spi2-core 2.2.2-0ubuntu1.1.)

This doesn't fix the crash. So either (1) this isn't the same bug after all, or (2) Ubuntu haven't fixed it properly. I'm not sure which. If you can verify #2 I'll go and raise a new ticket over there.

(Also worth noting that I have a machine at work, which was installed from scratch with Oneiric (rather than upgraded like this one, although my home directory and settings etc. have been inherited from machine to machine over the decades) on which amarok is working fine.)

The crash can be reproduced every time.
