Bug#340725: fails to raise windows

[340725deb.3.iridos at recursor.net]

The patch applies without problems to the metacity source package in
squeeze and fixes the tcl and python test cases as well the problem
with the program that caused me to search for the reason of the bug.

It would be nice to have the patch included into the squeeze package
if ever there will be a bugfix update for metacity in squeeze.
