[oe] devshell "No protocol specified"

[Douglas Royds]

Failing to get a devshell console. Fails for both XTERM and KONSOLE:

| No protocol specified
| xterm Xt error: Can't open display: :0

The failure is unique to one box (ie. it works fine on a different computer).

Invoking run.do_devshell.15108 directly succeeds, so the problem only occurs 
when we try to launch the devshell from within bitbake.

I used bitbake -D to see the list of environment variables that bitbake was 
unsetting. I tried listing the whole lot in BB_ENV_EXTRAWHITE, but still no joy.

Suggestions?
Douglas.
