Very curious.

What would be helpful here would be if you could reproduce the problem
while passing --debug or --dump?  --debug generates copious debugging
output to stderr; --dump takes a file argument, and when an error like
the one you see here occurs it dumps (slightly less) copious debugging
output to that file.  Either would probably be sufficient.

(Well, I guess it would also be useful if you could make the offending
CVS repo available, but I'm guessing from the branch names that that
isn't going to be possible :-).  You might want to look over the
debug output as well to double-check there's nothing sensitive there,
but I'm guessing it should be mostly okay, filenames are probably the
most sensitive thing that might be there.)
