testgtk.lisp problem

I upgraded clg to the latest CVS version but testgtk reported some weird errors.

I'm using SBCL 1.0.5 on x86-64 Linux, both multi-threaded mode
(started with clg-init-with-threading) and single-threaded mode gave
similar errors.

Here's the debug backtrace.

The value NIL is not of type NUMBER.
   [Condition of type TYPE-ERROR]

Restarts:
 0: [TERMINATE-THREAD] Terminate this thread (#<THREAD "gtk event
loop" {1000C5FCF1}>)
