Comment 1 Marco Martin 2014-03-28 17:07:22 UTC 
Can't reproduce here.
From the bt, seems an issue, maybe upstream in the QML layouts plugin from qtquickcontrols.
Are debug symbols for qt installed?

one thing i would like to have in the crash reports as a comment: Those bt are huge and only a small part is remotely useful, so I would invite to search for the useful part (quite often in thread 1, but not always, usually you see one thread doing something all the others in sleep)
in this case:

Comment 2 Bhushan Shah 2014-03-29 03:17:45 UTC 
Hmm, do you have something playing? If yes, crash will not happen.. I tried in both conditions.. i.e something is playing and nothing is playing.
Comment 3 Martin Klapetek 2014-03-31 17:37:16 UTC 
Can't reproduce either, all fresh + couple days old Qt.
Comment 4 Bhushan Shah 2014-04-07 11:33:50 UTC 
Can someone reproduce this? I can still reproduce this clearly reproduce that.. (updated qt)
Comment 5 Marco Martin 2014-04-07 11:58:43 UTC 
nope, can't reproduce at all here too
Comment 6 Bhushan Shah 2014-04-07 12:00:23 UTC 
Closing it then.. :)
