Trying to think in terms of robust general solutions to this problem, what
if update-manager were to notice when fonts were upgraded, and when they
are, shut down the GUI connection and reinitialize it? This might require
saving a bit of state information in update-manager in order to be able to
restore it.
Similiar in principle would be for the font libraries to notice when the
fonts have changed on disk and react accordingly, but since this obviously
hasn't been done yet and this problem has existed for years, we maybe
shouldn't count on solving that in the near term.
