The remaining problem is that python-xpcom does not work when it was not
previously installed but xulrunner-1.9.1 was.

Plus, xulrunner doesn't need python-xpcom. The problem is that xulrunner
trigger can't work when python-xpcom is only unpacked. It can only work
after python-support trigger has run (or update-python-modules has been
run from python-xpcom postinst, for that matter).

The root of the problem, really, is that python packages can't be used
when only simply unpacked.
