Application: dolphin (21.08.2)

Qt Version: 5.15.2
Frameworks Version: 5.87.0
Operating System: Linux 5.13.0-20-lowlatency x86_64
Windowing System: Wayland
Distribution: Ubuntu 21.10

-- Information about the crash:
- What I was doing when the application crashed:
I tried to create an .7z archive with LZMA(1) on Max compression level of 1186
files. There was a notifcation with a progress bar moving back and forth with
the words "compressing 1186 files" on it, then after a while this progress bar
stopped going back and forth and filled the whole bar, as in 100%, but it
stayed like this for a good amount of minutes and in addition Dolphin's
tile/entry in the task manager changed from blue to green. While i have left it
stay that way, i have tried to compress again a different set of 15 files with
the same archive format and settings as above. The same thing happened but
faster/it took less time. Then i clicked the stop button/cancel button for the
15 files - after a few seconds Dolphin crashed.

The reporter is unsure if this crash is reproducible.
