Bug#443557: cannot reload metacity after running compiz

[Lapse of Reason]

Package: metacity
Version: 1:2.18.5-1
Severity: normal

After loading compiz with "compiz --replace &" I can not load metacity
anymore unless I log out. When I try to run "metacity --replace" it
loads metacity for a second, but then immediately exits with status 0
and returns to compiz.

The version of compiz that I am running is 0.5.2-2.
