Reproducible: Always

Steps to Reproduce:
Before 2.4.1 it helps to unmount my external HDD where the media files are on. Then i starkt amarok and then i mount my external HDD.

But now amarok crashes always after start. It helps when I move .kde/share/apps/amarok/mysqle directory away. But then all my play counts are gone when i start with a blank database.

Actual Results:  
Amarok crashes.

Expected Results:  
Amarok should work.

I have a large Music Collection with more then 13.000 Files
