Truncated backtrace:
sessionproxy.py:132:get_torrent_status:KeyError: 'name'

Traceback (most recent call last):

Local variables in innermost frame:
keys: ['name', 'total_size', 'num_files', 'tracker', 'save_path', 'message', 'hash', 'comment']
torrent_id: 'd5295fcca17268ee8d92ba067a0830c3a4d9fca2'
self: <deluge.ui.sessionproxy.SessionProxy object at 0x2bcb590>
keys_to_get: []
key: 'name'

This is likely to be a race condition between a the on_status callback when a torrent is added and the get_torrent_status call.
