Hey Mike,
Indeed, I don't know how I ended-up with such a bookmark, but it
prevented me from git-cloning the repository (and the backtrace was
not very helpful at first).
But I'm still not sure what you mean by "deleted bookmarks" ?
I guess it's not "hg bookmark --delete", as it would not be listed at
all. Is it "hg strip some_changeset" that end-up deleting the
bookmarked changeset ? I think I've tested this use-case and it moved
the bookmark to a parent changeset.

Antoine,
