SUMMARY Ark crashed the plasmashell process when archiving (or ending to archive) a folder into 7zip default profile format (LZMA2, level 5/9 or 6/10) STEPS TO REPRODUCE 0. Download the https://mirror.koddos.net/manjaro/unstable/core/x86_64/glibc-2.33-5-x86_64.pkg.tar.zst file to Desktop. 1. Unpack it. You got another archive. 2. Unpack it into single folder. 3. Click on mouse's secondary btn on that Desktop folder. 4. Select `Compress` -> `Compress to...` 5. In the popped up archiving setting window I have `7z` format already selected, probably I use default settings for all. Click OK. Wait 10-15 seconds. Plasma panels disappeared and was restarted, core dump file appears. OBSERVED RESULT plasmashell crash EXPECTED RESULT No crash while Ark archiving things.

Even though the backtrace is completely different I'd say it's likely the same root cause as https://bugs.kde.org/show_bug.cgi?id=446049 Even if is isn't the backtrace isn't telling us anything useful I'm afraid *** This bug has been marked as a duplicate of bug 446049 ***
