thanks again for the very detailled response.

yes, that helps. This makes mission control starting:

rdorsch at paddy:~/SW.nobackup/tapioca$ ps uaxwww|grep mission
rdorsch  23435  0.1  0.1   4196  2456 pts/14   S+   20:38   
0:00 /opt/gtalk/bin/mission-control
rdorsch  23438  0.0  0.0   1636   552 pts/16   S+   20:38   0:00 grep mission
rdorsch at paddy:~/SW.nobackup/tapioca$

That is one step ahead :-)

I was hoping this was the last one, but there is another in front of me, 
empathy (mission-control in this case?) still does not find any plugin:

This is the dbus_daemon output:

Does anybody have insight why the telepathy-gabble plugin is not found?

I agree. But I want to have the install directory and the rest of the system 
(managed by apt) separated completely. And I hope that if I get it build it 
helps some Nokia Internet Tablet owners to just copy it onto their system an 
jabber to their Nokias from their Desktop.

I did not have dbus-1 files in ~/.local/share. But I need

cp -ra /opt/gtalk/share/mission-control/ ~/.local/share/

otherwise empathy segfaults.

I wrote a wrapper around mission-control which straces mission control. The 
output is at http://bokomoko.de/~rd/mission-control.strace
