Subject: ** Fix for bug #467892

2008-04-30  Milan Crha  <mcrha@redhat.com>

	** Fix for bug #467892

	* em-folder-view.c: (em_folder_view_open_selected):
	Do not inherit search filters when opening messages in new window.
	* message-list.c: (regen_list_exec):
	If we are called from folder_changed even, then keep the actually
	selected message so it will not disappear when user reads it and
	it doesn't belong to actual filter anymore.
