You current best solution to drop this from the clowncopter without 
loosing a local copy is:

$ hg pull clowncopter
# since the bad changeset is currently @
$ BADHASH=`hg log -T '{node}' -r @`
$ hg touch $BADHASH # get a new version
$ hg prune --hidden $BADHASH # say the old version is dead-dead
$ hg bookmark -r @~1 --force # move @ backward
# force the backward bookmark move on clowncopter
# and push the prune marker for the bad hash.
$ hg push -B @ clowncopter

(This is not viewed as an acceptable user experience)
