It is up to date. Here is my sources.list in case there is anything wrong here:

  deb http://ftp.us.debian.org/debian/ wheezy main
  deb-src http://ftp.us.debian.org/debian/ wheezy main

  deb http://ftp.us.debian.org/debian/ wheezy non-free contrib
  deb-src http://ftp.us.debian.org/debian/ wheezy non-free contrib

  deb http://security.debian.org/ wheezy/updates main
  deb-src http://security.debian.org/ wheezy/updates main

  # For skype:
  deb http://download.skype.com/linux/repos/debian/ stable non-free

As for the backtrace, I'll need some hints on how to do that. I
re-built the 'xfce4-session' package with debugging symbols and
attempted to get a backtrace of "xfce4-session-logout --suspend" per
these instructions:

    http://wiki.debian.org/HowToGetABacktrace

but I was instantly logged out of my session. I also tried to dump a
backtrace to a file using this trick:

    http://blog.cryptomilk.org/2010/12/23/gdb-backtrace-to-file/

but the resulting file contained only "no stack" and "no registers".
