Several segmentation faults after upgrade to Lenny
I just did a aptitude upgrade on an early lenny (testing) system to
lenny release, which has resulted in an unusable system. Several
programs (bind, apache, greylist and a couple of others) segfaults on
startup:

Attached is the strace output from one of the of the failing commands
(update-python-modules --post-install python-support.dirs). I'm not
strace expert, but it seems to fail on "futex(0xbfde8b00,
FUTEX_WAKE_PRIVATE, 1) = -1 ENOSYS (Function not implemented)".
My server is running as a xen instance on a 2.6.18 etch xen kernel. I
tried booting a 2.6.26 kernel as well, this didn't help.
