Btw, there's no easy / obvious way of deleting all the tags at once !
I can only delete them one-by-one...
Comment 2 Marcel Wiesweg 2012-12-30 19:15:32 UTC 
As there is no way to delete multiple tags at once, the bug is about a crash when you delete a single tag, isnt it? Is it reproducible for all tags, any time?
