Looks good to me.  LockError.__init__() should be calling 
BzrError.__init__(self), but it isn't like it did it before your fixes.

I also would like to see a comment like:
# Python 2.5 uses a slot for Error.message, so use a different variable
# name so it is exposed in self.__dict__

To explain why we don't want to use 'message'.

(Side note: I'd really like something like assertRaisesMsg, which checks 
the str() form of the exception. I know we've discussed having an 
assertRaises that returns the exception object, so you can inspect it.)
