Public bug reported:

While looking into something, I tried pulling  a branch of checkbox
using bzr.  This started creating a local branch of the current checkbox
trunk, however, after a certain point, bzr crashed with a traceback and
a partially filled directory.

bladernr at klaatu:~/development$ bzr branch lp:checkbox
