[Giuseppe Scrivano]

It fixes this error:

Traceback (most recent call last):
  File "virt-manager/virtManager/storagebrowse.py", line 271, in pool_selected
    pool = self.current_pool()
  File "virt-manager/virtManager/storagebrowse.py", line 238, in current_pool
    return self.conn.get_pool(row[0])
  File "virt-manager/virtManager/connection.py", line 645, in get_pool
    return self.pools[uuid]
KeyError: 'bd9fd5ec-a35c-d84a-b9b2-2aca98f733c3'
