'odd' error when DISPLAY not set.

[Ian P. Christian]

I suggest this error is a little misleading. I'm not sure if this
could be considered a bug, and if so - where the bug actaully lies.

"export DISPLAY=:0" fixes the problem (the var became unset as I was
working in a chroot'ed 32bit env within a 64bit platform)
