- What I was doing when the application crashed:

Finishing installing or updating. Previously tried to install krita and it didn't let me, then installed it crashed and then when updated the app it crashed again.

The crash can be reproduced sometimes.

*** This bug has been marked as a duplicate of bug 378339 ***

Comment 2 Christoph Feck 2018-01-15 00:26:06 UTC

Should we reopen bug 378339? Either the commit there was not sufficient to fix the issue, or it is not really a duplicate (see KF5 version).

Note that we also have related search crashes in systemsettings since its switch to the new kirigami UI.
