In my case this happens only when I eject USB drives. Unmounting works fine.
I couldn't reproduce the issue with pcmanfm. Using gio mount -e /path/to/usb doesn't return any errors.
Usually after several minutes I also get error message that says "Failed to eject "<filesystem label>". Timeout was reached."
Sometimes, about 30 minutes after ejecting the drive, thunar daemon segfaults. I sent the automatic crash report via apport.
