Comment 1 Marcel Wiesweg 2010-05-14 17:47:38 UTC

Is this reproducable? Any chance album2 was a subalbum of album1, so that while album1 was moved, at any point album2 would be moved as well?

There is a null pointer check missing, easy enough to fix, but I dont know why album2 got null while being dragged.

Comment 2 Raphael Ackermann 2010-05-15 12:31:37 UTC

I haven't tried to reproduce it. 
album2 wasn't a subalbum of album1 so no that wasn't the cause.

Crash should be fixed. Reopen if problems persist.
