Some additional information:

On both PCs I opened the file:
/var/lib/bluetooth/<local-bdaddr>/trusts
and wrote this line in it:
<remote-bdaddr> [all]
saved the file and tried again to connect via pand. Connection again 
didn't worked but after that, the entered line in the trusts-file was 
deleted!

Maybe this helps you to help me? :-)

Regards,
Steffen
