Ouch, that's convoluted.  What Adam was trying to do was in principle
correct.  It would be cool if someone who has the time to do so could
look over his test case to check whether he made some subtle mistake, or
if there is a problem in gtkmm.

Let's try to avoid suggesting work-arounds until we figured out what the
problem is.
