As Mike said if you have problems with your emails getting to Launchpad please do contact the launchpad team. With the information you provided in the first place we're unabled to reproduce the issue, might be only affecting you that's why we are asking to reproduce it with a newest version of metacity, are you able to do it? otherwise might be good to send this directly to bugzilla.gnome.org where the software authors are going to read about it and probably have a better clue of what's going on the package. Thanks.
