Ok.. Found the culprit..  I had several html select fields on this 
particular page and had callbacks such as :

   (html select) list: #('Blah' ); callback: [self error: 'Should not 
come here'].

Anyway, Seaside was complaining because in this particular case I was 
actually causing the registered
callbacks to be triggered (something I hadn't done when using the 
liveCallbacks).. In this case these
html select callbacks take 1 argument not zero as I've got them coded..

I also had the same problem with my html submitButton -- I had one arg 
specified but it doesn't get one..
Once I cleaned that up, my problems went away -- no more weird traceback.

That was one of the really odd things I've tracked down recently.. I 
guess it would have been nicer had
it told me what block it was executing (the debugger didn't make it very 
obvious), etc.. I'll know better
for next time..
