apport sometimes prints "Cannot open display" when run over ssh

Bug Description

repro:
Try to login to a machine which is standing at GDM and then run apport-collect.

Doing exactly that is a critically important use case for xorg crashes because if you login the xorg.log gets reset and whatever was in xorg.log.old is permanently lost.

Maybe this bug only affects the xorg hook for apport (not sure?)

This actually comes from xorg's package hook. I guess there's no way around having $DISPLAY set for some commands, but maybe it can be quiesced a bit. Something like this, perhaps:

  if os.environ.get('DISPLAY'):
      # do commands which need $DISPLAY
  # do commands which don't need $DISPLAY

This bug was fixed in the package xorg - 1:7.5+1ubuntu2

---------------
xorg (1:7.5+1ubuntu2) lucid; urgency=low

  [ David Planella ]
  * Completed internationalisation support for failsafeXinit (LP: #335678)

  [ Didier Roche ]
  * debian/local/Xsession.d/20x11-common_process-args: Add support for
    session command containing args (LP: #512235)

  [ Bryce Harrington ]
  * debian/local/Failsafe/failsafeXinit: Remove all use of dexconf, as it
    no longer does anything interesting. Instead, to restore a system to
    default configuration, just remove the xorg.conf after backing it up.
  * debian/local/Failsafe/failsafeDexconf: Drop script since it is no
    longer needed by failsafe.
  * debian/apport/source_xorg.py: Update info apport collects on X issues
    - Include make.log and dkms status info for proprietary drivers
    - Collect -nouveau version
    - Don't expect xorg.conf or Xorg.0.log.old to always be present
    - Don't run commands that need X if X is not available (LP: #368282)

  [ Timo Aaltonen ]
  * Add wacom back to -input-all.
