Bug 184207

Description of problem:

Clearlooks (and Bluecurve) crash GIMP when GIMP's main window is moved to the
second screen and the Display subpage is opened in the Preferences.

Version-Release number of selected component (if applicable):
GTK+ 2.8.11 (gtk-2-8 branch built 2006-01-20).
gtk2-engines-2.6.3-2

How reproducible:
Start GIMP (CVS HEAD 2006-03-05), move the main toolbox to the second screen and
open up the GIMP preferences. Then select the display subpage. 
  
Actual results:
