Bug 450187

Application: ark (20.04.2)

Qt Version: 5.12.7
Frameworks Version: 5.76.0
Operating System: Linux 5.3.18-150300.59.49-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.3"

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

After calling ark 20.04.2 from a root shell in OpenSuse Leap 15.3-2, I had selected a bunch of files and directories, recursively resulting in somewhat over a miliion files to be compressed into the archive. The crash happened when the progress box was present for some minutes but before or when it should start showing a percentage. The archive has not been created at all.

Sorry for beeing so unspecific, but If you feel this case should be tracked down, please feel free to ask me questions the answers to which might help you in finding the issue. I have called the same job again one time with the same result.

The crash can be reproduced every time.

-- Backtrace:
