I believe this may be a bug in our code. Could you attach the BT debug
text?  Does it say "QThread: Destroyed while thread is still running"?
It would also be important to know what exactly you were doing, i.e. how
many modules installing, did you cancel any, did this happen after all
was done... Sorry to ask these basic questions :) And also for the other
crash you mentioned.
