This is a stack overflow problem with CUPS being called out of a
thread.  CUPS allocates a lot of memory on the stack, and it was
overflowing the default 64 KB stack size.  Since that's all GThreadPools
allow, I upped the amount of stack size in gthread to be 256 KB
everywhere.  Yes, this is a hack, but I see no other way to handle this
unless the GThreadPool API changes, libgnomecups is rewritten again not
to use thread pools, or CUPS is updated to dynamically allocate memory
on the heap.  Other ideas are certainly welcome.

That said, given that this version of gnome-cups-manager uses
libgnomeui-2.7 functions, it should probably be moved over to MC, and
backed out of the FreeBSD ports tree.
