Bug#217731: Seems to have vanished---might have been a bug in a particular theme

[Bruce Stephens]

I was trying out various Nautilus themes, and when I'd finished, I
noticed that the proper desktop had reappeared.

Everything seems to be back to normal now (even sawfish seems to be
working again).

So I think this bug can be closed.  If I notice it again, I'll raise a
bug against the theme.  

I just tried going through the themes, and none seemed to trigger the
problem.  Might be one of these weird errors that's improbable, and
hard to reproduce.
