-- Information about the crash:
Sometimes while using kate if I try to use CTRL+TAB to switch between open
files the app crashes.
This has happened multiple times now and always after I use CTRL+TAB, but I
haven't been able to manually reproduce the crash after the fact. After a
restart kate just goes back to working perfectly fine until it doesn't.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
