If reading the bookmarks file, or re-importing the bookmarks from the rdf

2004-03-01  Christian Persch  <chpe@cvs.gnome.org>

	* src/bookmarks/ephy-bookmarks.c: (backup_file),
	(ephy_bookmarks_init):

	If reading the bookmarks file, or re-importing the bookmarks from the
	rdf file fails, back up those files so that the user can afterwards
	try to manually recover his bookmarks. Fixes bug #128308.
