Yep, I'm aware of that, I backed up my database and my pictures before testing.

> 3: Can you reproduce it? Do you have information where the other threads are hanging when the process locks? 

Yes, I can reproduce it every time when I try to copy my old digikam config over to my KDE4 home and restore the old databases.
There was another thread (sorry, didn't see that before), here are the backtraces for the two threads:
