Application: kate (18.04.1) Qt Version: 5.10.1 Frameworks Version: 5.46.0 Operating System: Linux 4.16.8-1-ARCH x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: I opened a file in Kate, and it offered me to restore its contents as it hadn't been closed correctly [1]. I couldn't display the diff [2], so I chose to restore the file. I then decided it wasn't worth it, so I hit Ctrl+Z to undo the restoration. Kate crashed. [1] I moved the file around before saving it (which, strangely, made kate display an authentication window upon hitting ctrl+s). [2] probably due to kompare or kdiff not being installed; though vimdiff -- or even diff -- could have been used as an alternative. The crash can be reproduced every time. -- Backtrace: Application: Kate (kate), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
