that's curious. I can't reproduce this. I am guessing that perhaps you 
have previously specified --db=./mtg.sql on the command line, that this 
option has been written to MT/options for reuse, and that monotone is 
complaining about "./" in the pathname, not in the directory walker.
that's probably a valid UI nit, though; when the (paranoid) local path 
object gets constructed with "./" in it, it throws. afaik this is fixed 
when building against boost 1.31.0, where I call the new "normalize()" 
function on the path before checking it. I'll file a bug to try to fix 
that on 1.30.2 as well. in the meantime, try with --db=mtg.sql. if that 
doesn't fix it, perhaps you can send me a --verbose log showing the problem?
in any case, the reason walk_tree_recustive() doesn't ignore "." or ".." 
is that they are not returned from a boost directory iterator. see:
http://www.boost.org/libs/filesystem/doc/operations.htm#directory_iterator

for the specification.
