I tried all three but no crash. 2447627 3 nate 2025-08-15 13:44:36 +0000 For me it crashes before the menu is even shown. David E tracked it down, and it's fixed/worked around with https://invent.kde.org/frameworks/kio/-/merge_requests/1975. The fact that it's mount-related may reveal that this is a problem specific to KDE Linux. This OS has some non-traditional mounts for its filesystem layout. 2450390 4 kde 2025-08-26 10:57:07 +0000 Git commit a8d2aaa1a8a9de8890c95b721a69b15886b50cd4 by David Edmundson. Committed on 26/08/2025 at 10:57. Pushed by davidedmundson into branch 'master'. guard mount point lookup Looking up a mount point for a path can fail. We should take care. A check later that sourceDevice is valid is also adjusted as comparing two empty mount points should not be treated as the same device.
