please split this patch in 2. I think these are 2 independant bugfixes. also please update the fate checksums so make fate does not break after either patch thx [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB When you are offended at any man's fault, turn to yourself and study your own failings.
