Thanks for the hint.  It fixed itself when I fixed another bug that (I
thought) was unrelated, and I pass along this other hint that may help
someone else: 

** Don't do a "list = g_list_remove(list, item)" inside the callback from 
a g_list_foreach(list).    It won't necessarily crash right there, but
funny pointer things will happen.

This is only one of my reservations about how g_list works, but I'm still
using them a lot because they're convenient and easily available anywhere
glib is.
