Bug 418660

Application: aqemu ()

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-8-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
- What I was doing when the application crashed:

I have a virtual machine created (for freedos). I'm trying to add a floppy disk from a disk image file. After some tries I discovered that even a simple click on the advanced button leads to this crash.

Regards

The crash can be reproduced every time.

-- Backtrace:
Application: AQEMU (aqemu), signal: Segmentation fault
