I've checked the git repository for glib at

   http://git.gnome.org/browse/glib/log/?h=glib-2-32

and there were very few changes between 2.32.2 and 2.32.3.  The only one 
that looks to me like it could have anything to do with our problem is 
the 2012-05-14 change to GConverterInputStream.  The change appears to 
be a pretty obvious bug fix, but I can imagine a scenario in which 
fixing the bug would result in the symptoms we're seeing.

I'm not going to speculate further until I can get access to an XP 
system to do some testing.  Or maybe someone who uses XP regularly will 
beat me to it.
