Comment 1 Andrew 2015-06-17 12:40:07 UTC

See it on Fedora 22 x64. Crash happens while restoring previous session. "kate --startanon" launches fine.

Comment 2 Andrew 2015-07-09 18:02:56 UTC

Still happens with kate-15.04.3-1.fc22.x86_64
Also have periodical crashes while usual work in Kate (both with some manual activity and not).
