--- Comment #2 from andy andy86@fastwebnet.it --- Update: I've found what do bug happen, the bug happen when there is a device in winecfg that point at not such folder.
For example wine auto-create device for mounting removable device, that device point to "/run/media/USER/DEVICE-LABEL", than device is removed from system (folder DEVICE-LABEL is deleted) but do not removed from wine (wine eject is not auto-call): at this point wine device point to not such folder DEVICE-LABEL.
Removing "temp" device problem is temporary fixed until next "temp" device is created.
Let's wait and see for wine 3.6
