SUMMARY
Attempting to delete a file within a cryfs or gocryptfs with dolphin creates the ".Trash-1000" folder but moves the file to "~/.local/share/Trash/"
With unencrypted volumes this is simply an inconvenience (and could lead to the root volume running out of space), however with encrypted volumes this risks leaking data.
I haven't tested other filesystems, but I would be surprised if no other similar projects were impacted.

STEPS TO REPRODUCE
1. Install cryfs or gocryptfs.
2. Create a new cryfs/gocryptfs volume and mount it to a local folder within the home directory.
3. Create a file within the mounted volume.
4. Delete it.

OBSERVED RESULT
1. ".Trash-1000" is created with the expected "files" and "info" folders, but the deleted file can't be found within them.
2. Checking "~/.local/share/Trash/" reveals that the deleted file has been moved there.

EXPECTED RESULT
1. The deleted file should be moved to the local ".Trash-1000" folder within the volume instead of "~/.local/share/Trash/"
