As noted in the RH bugzilla entry, this appears to be a SL build issue, not
an upstream bug.  A straight rebuild of SL's SRPM with no changes fixes the
problem.  Most likely there was a problem with the build environment used to
produce the SL binary RPM.

I would recommend that this be addressed with some urgency.  Given that
autofs attempts to unmount idle filesystems every 5 minutes, most affected
systems probably have many GB worth of core files sitting in / by now,
potentially leading to a full root filesystem and the myriad problems that
causes.
