>Related to/duplicate of bug 383828.

I'm not sure it is, there's no object being shared between two engines, and the trace is a bit different.

Do you still have the crash on launch?
If you can run it in valgrind that would be very useful.

Comment 3 rfe.gribovskiy 2018-03-22 02:38:52 UTC

After one of updates it works fine. Works on plasma version 5.12.3, framework 5.44.0, qt 5.10.0.
