Description Feufochmar 2020-04-03 10:23:00 UTC

SUMMARY
I sometimes encounter segfaults when pasting text into the editor in Kate.
When restarting and reloading the unsaved changes from the swp file, the inserted text is shown correctly pasted. However, the inserted text never appears in the editor when kate segfaults. So the crash seems to occur between the update of the swp file and the refreshing of the editor.

STEPS TO REPRODUCE
1. Paste text into the editor

OBSERVED RESULT
Segfault occurs sometimes.

EXPECTED RESULT
The editor is updated with the pasted text.
