Title:
  attempt to upgrade to saucy failed early with segfault

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  I attempted an only-slightly-premature upgrade to saucy using the
  usual "update-manager -d" command. It progressed as far as accepting
  my agreement to its warning that saucy is beta, then crashed out with
  a segfault. This is what I got at the commandline:

  rachel at twilight:~$ update-manager -d
  Checking for a new Ubuntu release
  authenticate 'saucy.tar.gz' against 'saucy.tar.gz.gpg' 
  extracting 'saucy.tar.gz'
  Segmentation fault (core dumped)

  I don't know where that core got dumped, I can't find it; not in my or
  root's homedir, not in /tmp (including not obviously in /tmp/ubuntu-
  release-upgrader*; everything else in /tmp too old to be relevant),
  /var/tmp, /var/crash. If you can tell me where it would have been
  dumped, in time for it to not get deleted by some automated process,
  I'll attach it. :-)

  In /var/log/syslog:

  Similarly at the end of dmesg output (earlier output from too long ago
  to be relevant):

  [450419.246918] saucy[13491]: segfault at 8 ip 00007ff9aeb8e03f sp
  00007fff74322890 error 4 in libGL.so.313.30[7ff9aeae9000+cf000]

  As it looks relevant, I have nvidia-313-updates installed:

  rachel at twilight:~$ apt-cache policy nvidia-313-updates
  nvidia-313-updates:
    Installed: 313.30-0ubuntu1
    Candidate: 313.30-0ubuntu1
    Version table:
   *** 313.30-0ubuntu1 0
          500 http://gb.archive.ubuntu.com/ubuntu/ raring/restricted amd64 Packages
          100 /var/lib/dpkg/status

  Some more machine context, as I'm not sure what would have been
  harvested automatically, or what would be relevant:

  GPU is a geForce 210 (GT218); running two 1080p resolution monitors
  via dvi and hdmi ports. update-manager was being run on the secondary
  (hdmi-connected) monitor.

  Synergy server is running on this machine, its client being another
  Ubuntu system already upgraded to Saucy (which doesn't have nvidia
  graphics).

  I guess if I wanted to push through with an upgrade immediately I'd
  instead try it server-style, using do-release-upgrade, but I reckoned
  as we're close to release, someone might want to have at this one. :-)
