Are you running Marco's single engine branches?
Comment 2 Hrvoje Senjan 2015-05-31 22:12:54 UTC 
Nope. KF5 & Plasma master + Qt 5.4.2 branch.
Comment 3 David Edmundson 2015-05-31 22:30:25 UTC 
OK, must have fewer threads because we're midway through shutting down.

Will investigate sometime.
Comment 4 Andrew Chen 2015-07-07 23:15:19 UTC 
Hi,
I also have this bug. It is quite annoying because plasmashell crashes and displays an error dialogue every time I logout/shutdown.
The bug is triggered by (not sure if caused by) commit 1f9c20e4c4c25f5df3593792f5166af3eeee6068 in plasma-desktop. Reverting the commit does fix this problem (but not sure if it causes other problems).
Comment 5 Kai Uwe Broulik 2015-07-08 09:57:10 UTC 
I can confirm that reverting the mentioned commit "fixes" the crash, so apparently on shutdown the containment's corona is already gone and then m_containment->corona() ->availableScreenRect(screenId) breaks on a dangling pointer?
Comment 6 Kai Uwe Broulik 2015-07-11 00:07:53 UTC 
Git commit 4942878b67c6a5ae82df11264eb751944cea4a69 by Kai Uwe Broulik.
Committed on 11/07/2015 at 00:06.
Pushed by broulik into branch 'master'.

Clear view lists in destructor

This fixes a crash on shutdown when it has already deleted its
views but someone calls into availableScreenRect
