Can you try guessing which part of the expression could have barfed?

When some Lisp expression eval'ed by the display engine signals an
error, that error is caught and the message is written to *Messages*.
That's because redisplay cannot possibly let the message appear in the
echo area, as this will cause another redisplay, which will again
signal an error, and so on, ad nauseam.

So the problem here is that an error was signaled during evaluation of
a Lisp expression.  Are you sure that the cause was C-g?  The fact
that you see "Quit" does not yet prove it was a C-g that caused that.

Print where?
