Does "all the gstreamer stuff" include your-defined bus watch?

It's very easy to check, who calls this function - just run your app in gdb
and put a breakpoint inside the function. Then use the 'bt' command to
display the backtrace.

Googleing for the "Qt polls glib main loop" shows some messages, suggesting
that the work on uniting main loops or QT and GLib were on their way in
2004.
