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: Thread 1 (Thread 0xb2026780 (LWP 2162)): [KCrash Handler] #7 0xb74cd5a7 in QQuickItem::~QQuickItem() () from /usr/lib/libQt5Quick.so.5 #8 0xa8717bbb in ??

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.
Can't reproduce either, all fresh + couple days old Qt.
Can someone reproduce this? I can still reproduce this clearly reproduce that.. (updated qt)
nope, can't reproduce at all here too
Closing it then.. :)
