"Lock already taken" while trying to remove a VM

[marmarek]

Clicked usbvm, clicked shutdown, while it shuts down clicked for vm
properties and clicked on other vms (vm manager was irresponsive),
then it showed that VM is stopped - requessted VM manager to remove
usbvm, then got this bug:

----
line: raise QubesException("lock already taken")
func: lock_db_for_reading
line no.: 606
file: /usr/lib64/python2.7/site-packages/qubes/qubes.py
----
line: self.qvm_collection.lock_db_for_reading()
func: get_vms_list
line no.: 521
file: /usr/lib64/python2.7/site-packages/qubesmanager/main.py
----
line: vms_list = self.get_vms_list()
func: fill_table
line no.: 555
file: /usr/lib64/python2.7/site-packages/qubesmanager/main.py
----
line: self.fill_table()
func: update_table
line no.: 649
file: /usr/lib64/python2.7/site-packages/qubesmanager/main.py

after pressing OK got message "VM usbvm has been removed", at that
time VM manger showed no VMs at all - just empty screen with two color
wide lines.
