Application: amarok (2.6.90)

-- Information about the crash:
- What I was doing when the application crashed:
When I first started amarok 2.7 beta, a message that the database is being upgraded appeared and amarok crashed afterwards (the main window didn't even show up).
Now amarok crashes everytime I try to start it, but without a message that the database is being upgraded.
The crash can be reproduced every time.

I can confirm that it doesn't crash anymore.

> I can confirm that it doesn't crash anymore.
Great, thanks a lot!
This should be a work-around:
don't store Last.fm username and password in plain-text: remove the entries tom .kde/share/config/amarokrc (search for Service_LastFm)
I can confirm that the workaround (editing amarokrc) worked for me - thanks

New crash information added by DrKonqi
amarok (2.6.90) on KDE Platform 4.9.4 using Qt 4.8.4
- What I was doing when the application crashed:
Exactly as explained before, I started Amarok after updating it to 2.6.90 (Gentoo masked packages).
After the database upgrade process ended, Amarok died.
Any attempts to start Amarok will crash consistently.
Rebuilding without lastfm support allows Amarok to start. Ie, in Gentoo, disable the "lastfm" USE flag.

this bug has been already resolved, unfortunately only after 2.7 Beta was released. There is no need to re-report unless you are able to reproduce with a version already containing the commit.
Please, use a work-around from comment 4 or update to amarok-9999, it is easy now that you have added kde overlay.
