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".
