Comment 1 Thomas Göttlicher 2010-04-09 12:19:49 UTC

According to the backtrace it crashes somewhere deep in libqt4.

Dirk, do you have an idea what's wrong?

Comment 2 Dirk Mueller 2010-04-09 12:56:57 UTC

both threads are waiting (one in select(), the other in poll()). thats not the cause of the backtrace. 

can you reproduce it? try valgrind.

Comment 3 Forgotten User 10buyl7JnO 2010-04-09 12:59:14 UTC

I can reproduce every time. Should I run in valgrind and post output?

Yes, please. Thank you.

Created attachment 356151 [details]
valgrind output.

Comment 6 Dirk Mueller 2010-04-22 08:39:20 UTC

there is no crash or anything in that valgrind output? did it "crash"?

Comment 7 Forgotten User 10buyl7JnO 2010-04-22 10:04:08 UTC

I think it hanged at least. Not sure about crash. It didn't do anything and stayed in same status for long time. It never finished update of the package I selected.

Hanging progress sounds like bug #578988.
