Description Marco Cilloni 2018-03-27 10:12:53 UTC
Application: kate (17.12.3)

Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.15.11-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Sometimes (almost always), after double clicking a file in Dolphin, if Kate opens and I quickly try to scroll using the right bar, Kate receives a SIGSEGV. 
I am using Wayland; I do not see this behaviour when manually launching Kate from a CLI.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
