[Robey Pointer]

Pulling a branch is giving this error in tip-of-tree bzr.dev:

bzr: Changeset entry for TREE_ROOT-20050807194350-6e6d329ed3636ad5  
(./.) is invalid.
file ./. has "TREE_ROOT-20050807194350-6e6d329ed3636ad5" id for both  
self id and parent id.

   at /home/robey/code/bzr.dev/bzrlib/changeset.py:564 in __init__()
   see ~/.bzr.log for debug information

(It does not actually write anything into ~/.bzr.log, and hasn't  
since late July -- which may be a separate bug.)
