New crash information added by DrKonqi

dolphin (21.11.70) using Qt 5.15.2

- What I was doing when the application crashed:
With are compress a directory containing the kernel source files. At some point during the process dolphin crashed.

After upgrading Plasma to version 5.23.0, Dolphin also crashes when you pack a file or folder to 7z.

When packing to other types of packages, e.ZIP,g. after packing, a new Dolphin tab opens with a view of the catalog from which the packaging was made.
I don't know if this last Dolphin behavior is normal or if there is a setting that causes this behavior.

Below are the software versions:

New crash information added by DrKonqi

dolphin (21.08.2) using Qt 5.15.2

- What I was doing when the application crashed:

Trying to compress a 7z file

- Unusual behavior I noticed:

It segfaults and crashes dolphin

- Custom settings of the application:

Not much. I disabled confirmation messages and enabled Text file previews. These don't seem related to the crash though.

New crash information added by DrKonqi

dolphin (21.08.1) using Qt 5.15.2

- What I was doing when the application crashed:
Compressing a file with 7z LZMA2
- Unusual behavior I noticed:
The application kept saying the compression was happening when it already finished. Cancelling the compression made the application crash.
- Custom settings of the application:
None.

dolphin (21.08.2) using Qt 5.15.2

- What I was doing when the application crashed:

I was compressing a directory with Ark using 7z and password encryption.
Most of the time Dolphin crashes right after the compression has started but the archive is ok and it is not corrupted.
Sometimes Dolphin crashes only when I press the stop notification button, same as bug report 442774.
https://bugs.kde.org/show_bug.cgi?id=442774

- Custom settings of the application:

Dolphin is in details view mode.
Breeze dark theme is active.

dolphin (21.08.2) using Qt 5.15.2

- What I was doing when the application crashed:
I was archiving a directory with options of 7zip, max compression and LZMA.
Dolphin crashes everytime when the archiver is about to finish and show
the compressed archive in a new tab in Dolphin.

It is reproducible with the same compressing configuration.

dolphin (21.08.3) using Qt 5.15.2

- What I was doing when the application crashed:
After moving a newly created .7z archive to trash and attempting to create it again with the same filename Dolphin crashes. The archive is created successfuly. The crash only happens when the name of the archive matches the filename of a file that was moved to trash. Otherwise a different behaviour is observed (described below).

- Unusual behavior I noticed:
I compressed a folder in Dolphin to a .7z archive. A notification popped up in the bottom right corner of the screen, as usual. However, it never changed its status to 'Finished'. The archive was created successfuly (as far as I can tell) and can be opened without issues. The notification remains stuck at full progress bar forever. This happens every time a new .7z archive is created. Compressing to .zip for example finishes as expected.

- Custom settings of the application:
None

I can confirm these 2 behaviours, which Vladimir Garistov has described perfectly.

I am using Gear 21.08.3, Plasma 5.23.3, Frameworks 5.88.0, Qt 5.15.2.

There have been multiple bug reports raised and "fixed" and "closed" around doing 7-zip compression from Dolphin context menu. It worked just fine until Gear 21.08.2.

I cannot understand why it is taking so many incremental bug fixes to restore behaviour which existed in Gear 21.08.1.

Surely it would require less effort to look into the cause of that regression?

dolphin (21.08.1) using Qt 5.15.2

- What I was doing when the application crashed:

After attempting to compress a file to a 7zip archive (a small file), the operation never seemed to complete. Eventually I attempted to stop the compression operation using the notification on the system tray, by hitting the big square stop button. This caused dolphin itself to crash.

The fix should be available in next maintenance version of Dolphin 21.12.1 as stated in the version fixed in field.

Anyone able to make split volume 7z archive via dolphin? there seems to be a issue now with splits that are not even megabytes
1.5 gets treated at 1 and 0.5  is treated as do not split, guessing this fix broke that, guess that is better than crashing though...
