*** This bug has been marked as a duplicate of bug 381814 ***

Comment 2 Christoph Feck 2017-11-08 19:29:21 UTC

The backtraces are unrelated.

This one comes from Attica::BaseJob::finished(), while bug 381814 comes from KActionConflictDetector::eventFilter(). The latter is possibly a duplicate of bug 386347 and/or bug 386015, since both come from QQuickItemPrivate::deliverKeyEvent().

Comment 3 Aleix Pol 2018-01-29 16:01:24 UTC

Is it still happening? If so please reopen with steps to reproduce.

Comment 4 Christoph Feck 2018-02-14 15:17:40 UTC

No response; closing. If you have new information, please add a comment.
