Sentry Crash Report:

Description George Baltz 2010-02-23 18:03:04 UTC 
Application that crashed: amarok
Version of the application: 2.2-GIT
KDE Version: 4.3.4 (KDE 4.3.4) "release 2"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-0.1-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

What I was doing when the application crashed:
Reproducable - clicking close during initial scan of USB storage device (MSC mode, not MTP)

Looks like the collection object(s) have been destructed out from under the scanning code.

Can you still reproduce this and send us a backtrace in Amarok 2.3-GIT?

Comment 3 Sven Krohlas 2010-05-11 17:54:05 UTC 
Mass closing NEEDSINFO bugs with no comment for at least 31 days.

Dear reporter,

thanks for your feedback. For efficient bug triaging we need not only one report but also constant feedback about the status of an issue, at least when we ask for it.

If your request is still valid in our latest release in your opinion (2.3.1 beta 1) DO NOT REOPEN THIS BUG but file a fresh one instead. Developers need clean bug reports to be able to work efficiently. Provide at least a step-by-step guide on how to reproduce the issue, a backtrace in case of a crash and debug output if appropriate.

And remember:
* One issue per bug. Small, clean bug reports are best to work on.
* Search for duplicates. Hint: we have useful categories for that. :)
