Ah-ha, that was it - we had some images with &'s in them that was
screwing things up.  E.g., 'Fruits & Vegetables'.  As long as the new
code also accounts for that, it should be good.  Thanks for looking into
it.

Sounds good.  Fwiw, early on Inkscape also had a lot of problems with
UTF8 encoding errors (caused a lot of crashes when used with foreign
language settings).  Jon Cruz and others added a lot of glib's UTF8
handling code to fix these things.  Hopefully Unicode::MapUTF8 will be
sufficient to take care of this for us.
