Also, this branch has never been committed to using bzr and bzr-svn.
All work has happened using plain svn.  Merges from trunk were done in
the old-school svn way, by someone of questionable merging skills.  If I
want to look and see what the differences in the properties are from the
time the branch was created until now, it looks like so:


$ svn diff -N -r 33812:HEAD
https://svn.foobar.com/imrs/branches/paging_optimization

Is it relevent that the two bzr revisions that seem to be causing this
error are the two revisions that are different since this branch was
created and now?
