DCOP ' Couldn't attach to DCOP server'

[Per Winkvist]

Hi,

If I start KDE and then switch to a text console or telnet to my computer and 
run dcop I always get 'Couldn't attach to DCOP server'. For a couple of 
months ago dcop spit out a message saying that I should set DISPLAY. Nowadays 
it doesn't do this. Setting the DISPLAY to :0.0 makes dcop do what I want.

The following patch sets the DISPLAY upon error and tries one more time which 
works great for me. 

Any comments  ?
