Are you using the embedded database or an external MySQL server? Strange we haven't seen this crash reported yet although Amarok 2.6 is out since August
Comment 2 Miras1990 2012-12-13 14:53:15 UTC 
I use the built-in database. In Kubuntu 12.04 all is ok.

Thank you for the feedback. What exactly are the steps to reproduce this crash? I can't reproduce this at all.

This is a crash on when closing Amarok, right?

Well, no, the description says otherwise.

Miras1990: please give exact steps on how to reproduce this crash, else the bug report is not really helpful.

Amarok crash when I wanted to update the music library, but before the operation turned music.

I do not know English well so I used Google Translator.

With the same Amarok version? Then it was not an Amarok bug.
