Comment 4 David Edmundson 2020-02-18 08:40:24 UTC 
Git commit 5c7ee50bf900666efa44439a4f4a12ec5df986f9 by David Edmundson.
Committed on 17/02/2020 at 23:31.
Pushed by davidedmundson into branch 'master'.

Don't double delete CommentsModel

Summary:
CommentsModel instances are owned by the engine.

They are fetched through a getter with a cache, so ownership has to stay
that way.

QuickItemsModel should not be deleting them.

Test Plan:
Got a valgrind log of the crash, which showed the issue
(see attached bug report)

Afterwards:
Opened systemsettings, opened comments dialog
Closed systemsettings
