MemoryError in socket.read during fetch of knit repository

When I try to checkout a repository via http, I get this error:

Looks like

http://bugs.python.org/issue1092502

and

http://bugs.python.org/issue1389051

[Aaron Bentley (abentley)]

Certainly related, and many of these will be cleared up by the same fixes.

[Martin Pool (mbp)]

The two Python bugs that Aaron pointed to seem to have been fixed in python2.5; if you retry using python2.5 and a recent bzr this should be fixed.
