Bug 353361

Application: plasmashell (5.4.1)

Qt Version: 5.5.0
Operating System: Linux 4.2.1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I clicked a text file in Dolphin. Plasma switched from desktop 1 to desktop 2 where Kate was already open to open the file in a new tab. I immediately switched back to desktop 1 which resulted in a crash. 

I can always reproduce this crash if I switch back to desktop 1 within about 1-2 seconds (either using keyboard or scrolling on the pager on my panel). It doesn't crash if a second instance of Kate is open in any desktop, if I close Kate before switching back, or if I switch to desktop 3 instead of 1.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
