Good point.

Here is the corresponding traceback from '$HOME/.bzr.log':

=====

That gives a pretty big clue: This repository is on a FAT16
filesystem, and I'm asking it to update a working tree containing
symlinks.

Should I expect that to work?

If it is to fail, I would at least expect a more sensible error
message, indicating what operation is failing, and exactly which file
in the working tree is being updated at the point of the failure.
