exceptions.KeyError on console webpage because of a weakref

[Martin Nyhus]

exceptions.KeyError is sometimes thrown by the web pages because of a time-of-check time-of-use problem with a weak reference. This was reported as upstream bug #2162 and at least partially fixed in commit 20a8fc09 which has not been backported to 0.8.5 / Ubuntu 12.04.
