This should be fixed in rawhide. The underlying problem here is that we're still trying to calculate the space needed for LVM based on the old partition layout, not the new one we've just created.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle. Changing version to '11'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
