The direct cause of the assertion failure is that pull is trying to
remove the file id from a file with no file id.

I really don't know how we could get there, though.

I would try reverting, and if that didn't work, I would try making a
lightweight checkout.

This bug is happening when modifying your local working tree.
Historical data shouldn't matter for that.

This conflict here is that you've deleted these files in one place and
renamed them in another place.  Bazaar can't tell that they were
automatically renamed.
