Does this happen more and have you seen it happen with the latest SVN version ?

So far it happened two times. Will check with the latest SVN in comming days, now I'm suffering chronical lack of time :/

Another crash with svn 541634. (stopped all torrents-> exit-> crash)

That's a weird one,it happens when we add a string to the log viewer and then Qt starts drawing that and it crashes. Which is very strange. This looks like a bug in Qt.

I've seen this crash too. I'll try getting more info...
