Subject: Re: BUG? atleast >=2.6.19-rc5, x86 chroot on x86_64

i know i said i suspected this was another bug, but i have revised my
suspecisions, and i do believe its in relation to x86 chroot on x86_64
install, as it has happened with more stuff now, inside the chroot, and
only inside the chroot, while the same apps dont do it outside chroot.

2.6.19 release is affected too
