I can't get this crash to happen. Do you copy, link or move it? (In reply to Akseli Lahtinen from comment #1) > I can't get this crash to happen. Do you copy, link or move it? I tried all three but no crash. 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. 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.

Created attachment 184023 [details] .desktop file STEPS TO REPRODUCE 1. Put the attached .desktop file in ~/.local/share/applications/ 2. Run `kbuildsycoca6` 3. Drag the .desktop file to the actual desktop OBSERVED RESULT Plasma crashes. 100% reproducible for me.
