Yes, this indicates that it should work now. However, it also seems that
original bugreport is because one corrupted volume (like your leftover)
stopped LVM scanning altogether (probably some race condition made it
either first or last scanned). Attached patch will fix it. Note: error
message is legitimate and won't go away with this patch. To fix the
basic problem you need to clear the stale signature but it's potentially
dangerous operation and with the fix the effects should be reduced to a
single error message.
