Comment 1 Kevin Funk 2014-01-24 10:43:49 UTC 
Does anyone have an idea why this could crash? There's no concurrent access to the QHash VariableMap inherits from, after all. My only explanation why this could have crashed in the first place.

Comment 3 Milian Wolff 2015-04-30 10:29:02 UTC 
The cmake plugin must wait for its import jobs before unloading itself. It's generally an issue we have with non-killable jobs that might lead to crashes on shutdown (which is why we warn about that in the runcontroller).
Comment 4 Kevin Funk 2016-09-08 10:57:33 UTC 
Should be fixed by:
