Bug 486414

Application: kate (24.02.2)

Qt Version: 6.7.0
Frameworks Version: 6.1.0
Operating System: Linux 6.8.7-300.fc40.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 40 (KDE Plasma)"
DrKonqi: 6.0.4 [CoredumpBackend]

-- Information about the crash:
I wanted to view a log file (~/var/app/org.kde.amarok/data/amarok/mysqle/aria_log.00000001)
I launched Kate and drag & dropped the file wich caused the crash.
After that I found that the file was a small (16Kb) binary file.

The crash can be reproduced every time.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
