Tcl/Tk errors

[Theodore C. Belding]

Hi-
I wrote up a version of Conway's Life, based on heatbugs (to learn Swarm).
I'm getting a slew of runtime errors like the following.  I probably made
an obvious mistake in my code, but for future reference, is this stuff
coming from libtclobjc, from tkobjc, or straight from the Tcl interpreter,
or elsewhere?  Can anyone tell me how to interpret these error messages?
Is there a central error routine in any of those libraries that I could set
a gdb breakpoint in, to break whenever one of these errors gets printed?
Or any debugging options? Thanks!

PS The program seems to work correctly otherwise -- guess even I can't
screw Life up...
