bzr-hudson fails on slave nodes

bzr-hudson (revno 10 in trunk) fails while trying to perform the initial check out when building on a slave node launched via ssh. Unfortunately, I am currently unable to test this on slaves launched with any of the other methods.

log:

I have tried this with the slave running on two different systems (one is the same system running the master):
