in messages log: first vfprintf entry starting at may 4th: firefox: vfprintf %s NULL in "%s: Resetting desktop app info dirs from %s to %s" a few times per day, all with firefox The first entry on may 4th was while updating packages, among them firefox. I still have a log of package update if anyone is interested. Regards Markus
