Hmm?  Depends on the repository - I don't really a have a canonical one,
and I usually only make them available on HTTP when I want to make some
code available for review...  Patches on top of either the main[1] or
the crew[2] repo are usually fine...

The prechangegroup hook is called by the local hg before adding the
revisions to the repo.  IOW, it looks like a problem on your end.

If this is the same "prechangegroup.mq-no-pull" from the wiki, it should
only fail if the repo you're pulling into has mq patches applied, which
is never the case for clone...  Was this with an unmodified hg?  This
hook depends on the exit status of hg qtop...
