remote repo wedged after interrupted transaction (BB-1001)

I managed to get stuck in a situation that seems unrecoverable from the web UI, by hitting ^C during a push. Now every time I try to push again to the freebsd-head mirror I keep here I see:

{{{
keramida@bokos:/hg/bsd/head$ hg push bb
pushing to ssh://hg@bitbucket.org/keramida/freebsd-head
αναζήτηση αλλαγών
απομακρυσμένο: abort: abandoned transaction found - run hg recover!
abort: unexpected response: empty string
keramida@bokos:/hg/bsd/head$
}}}

Is there some way I can recover the remote bitbucket.org repository by running "hg recover" on it?
