-- Information about the crash:
- What I was doing when the application crashed: Alt-tabbed into KATE
This issue happens very rarly, I'm unable to reproduce this issue even If I
want to, but it does happen sometimes when I'm writing something.
This issue becomes pretty serious when I'm researching something, and writing
those down on Kate, as I need to switch between my browser and Kate quite
often. This causes Kate to crash at least once, and everything I've written
that point is lost.
My OS is Kubuntu
The crash can be reproduced sometimes.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
