I've had a look back at the thread where that happened, and your comment
was:

: OK, GTK tries to update every toplevel window in its list when the
: theme changes, even if the window has actually been destroyed. Windows
: are not removed from the list until their ref-count is zero. Python's
: garbage collector doesn't drop the refcount until it decides to do a
: clean-up.
: 
: As a quick fix, I've changed LookAndFeel to do a gc.collect() before
: changing the font, which ensures that the just-closed FontSelector
: isn't still hanging around. I'll file a GTK bug...

So it looks like it's only needed if the font or theme has changed *and*
another window has just been closed. That explains the gc.collect(), but
I don't see why the g.idle_add() is necessary too.
