Comment 3 Tomas Mraz 2008-11-27 16:16:40 UTC
I strongly suspect there is some problem in the libnss_nis nsswitch plugin.

Can you please install openssh-debuginfo and glibc-debuginfo and try to obtain the backtrace again?

This is a duplicate of bug 473081 & bug 473073. See patched .so file in 473073, and follow the instructions there to confirm.
