The admin (me) did see your comment but didn't find time yet to investigate 
the problem in great length :)

However, it seems that Henry Vermaak gave you a solution. I am glad he did, 
because I have written a complete set of D-BUS components which I was about 
to publish, and they would suffer from the same problem when used in a GUI app.
So now I know that I should create an integration with the Lazarus message loop.
