Yes, but completely unrelated.
You can create threads in your program. And you can set a receiving filter
function. libdbus has no control in which thread the filter function is
It's up to you to run dbus_connection_dispatch (or any of the other
dispatching functions) in the correct thread.

What function did you call in the processing thread? If you called
dbus_connection_read_write, it'll block on the socket access. You need to
release the transport to make other threads work.
In other words, you need a full mainloop in your thread: a select(2)-based
socket notifier and timer implementation.
