I am not sure - I don't have x64 installed - and I am reluctant to do - I don't have a spare partition to use.
 
It would take a lot of effort to completely recreate my settings on an x64 - unless I have misunderstood what you asked.

Tony Flury, thanks for the follow up information.

As upstream has a support focus on x64, does this still occur if you
switch to this?

Title:
  I get an "error report" popup on log-in

Status in xorg package in Ubuntu:
  Incomplete

Bug description:
  This doesn't occurr on every login, but it does occurr on the
  majority.

  From the crash report it seems to be Xorg, rather than Nautilus
  desktop.

  There are no obvious symptoms of this crash - i.e. everything seems to
  carry on regardless.

  I am reporting this against xorg, due to the existance of
  _usr_bin_Xorg.0.crash in /var/crash - I assume that all the
  information you need has been extracted below ?
