Hi,

I'm having trouble running KDE 4 programs in a KDE 3 session, which I think 
should be possible.
 
The problem is that when KDE 4 programs starts up, they naturally load the KDE 
4 session(KSysoca runs, DCOP server starts, etc) and this crashes with the 
pre-existing KDE 3 session. For example, Konqueror fails to contact 
KLauncher, KMail can't start the kioslaves, etc. Judging from console output 
it looks different KSycoca programs fights on updating the database, which 
could then be the explanation to why the KDE 4 program after a while fails to 
run(it load files).

What I find strange, is that I shouldn't encounter this, because I've set the 
KDETMP and KDEHOME environment variables to something different, in the 
konsole session I run the KDE 4 program from.

Someone perhaps knows how I can run KDE 4 programs in a KDE 3 session without 
trouble?

(LD_LIBRARY_PATH was used to make the kde 4 program locate the kde 4 
libraries.)


Cheers,

		Frans
