I tried to connect to my self-made dbus server using Qt4 (address: 
unix:path=/tmp/mydbusserver) , and it hangs in 
In my server I receive two signal messages with interface 
org.freedesktop.DBus, object /org/freedesktop/DBus, and member NameAcquired, 
sender is org.freedesktop.DBus. 
And I receive them in the moment when my Qt applications tries to connect.
I'm a bit confused, does the Qt application send these signals ?
But they say the sender is org.freedesktop.DBus.
