Hi Marco,

Could you please provide a test that shows this
problem so that I can ad it in the function?

It would be even better if you could provide the
proposed changes in the form of a Mercurial changeset,
but if that's not possible I can create the changeset myself.

thanks,
c.

should be changed to
