Application: k3b (19.04.3)

Qt Version: 5.12.4
Frameworks Version: 5.62.0
Operating System: Linux 5.3.0-40-generic x86_64
Distribution: Ubuntu 19.10

-- Information about the crash:
- What I was doing when the application crashed: Try to load a 42GB ISO file

- Unusual behavior I noticed: The system went slow in the middle of loading and the progress bar froze at roughly 10% status and then k3b and kdeinit both crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: K3b (k3b), signal: Segmentation fault
