I attempted some basic debugging but although I can put a stop in the
32-bit code and halt within "configure_event" (which is where the
variables in question are mostly set), this doesn't work in the 64-bit
version (see sample session below).
I wonder if this is the root of the problem - the assertion is
correctly flagging that these two variables have not been set and
somehow the assertion is being invoked out of sequence.
coclass 'jglcanvas'
13!:3 'configure_event 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
18 19 20 21 22 23 24 25 26 27 28 29 30 : 0 1 2 3 4 5 6 7 8 9 10 11 12
13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30'
coclass 'base'
NB. Just because I'm paranoid...

NB. You can see that these two stacks differ about 5 calls deep, at
"gtk_show[8]" (32-bit) versus "gtk_show[6]" (64-bit).
