Can't start BApplications through ssh / with other user

[pulkomandy]

• Create an additional user for ssh access
• Ssh to your haiku computer, and try to run a BApplication
• The application silently stops.

Syslog has this message:

DAEMON 'app_server': Cannot initialize Desktop object: General system error
KERN: Could not initialize graphics output. Exiting.

This happens with vim, unzip, and DumpRenderTree. It's either because of using ssh, or because the new user doesn't have the right permissions. At least a warning to standard output, instead of the syuslog, would be nice. A fix to make this working would be even better.
