SUMMARY

I have a multi user system.
When I plugin my external hard drive under user "A" and mount it using Plasma's "devices" plasmoid, it'd expect that it becomes unmounted if I log out.

However, if I logout and switch to user "B", the device appears to be still mounted.
If I try to open the folder via "device" Plasmoid" or to remount it there, I see the error message attached:

> "Could not execute command. The file or folder /run/media/$USER/12345ABCDEF does not exist."

Plugging the external HDD out and back in "fixes" the problem.


STEPS TO REPRODUCE
1. Login as user "A"
2. Mount external HDD via Plasmas "devices" Plasmoid
3. Logout
4. Login as user "B"
5. Try to open or remount the HDD via Plasmas "devices" Plasmoid

OBSERVED RESULT

Device is not useable. Error message appears.


EXPECTED RESULT

HDD (partitions) can be mounted again.

If I instead of step 5. press "unmount device" it completely disappears from the "devices" Plasmoid.
