I've recompiled glib, gtk+, and libglade w/ debugging turned on and will include
a small section of the backtrace again. I can't seem to get to the bottom of
the backtrace (it's up to about 3000 lines right now) . . . it just keeps
spitting out the same 5 or 6 functions (lines 3 through 7 repeat over and over,
indefinitely). Please let me know if this helps and if there is anything else
I can provide.
Thanks in advance!
