gdb log 1

The weston-launch program always crashes with a SIGHUP (Hangup) regardless of
how Weston exits.  The SIGHUP always occurs during the call to pam_end() but
with various locations within that call.  See attached gdb backtraces for more
details.  Was able to verify this on two separate Fedora 17 (64 bit) OS's. 
However, could not produce the issue on the Ubuntu OS.
