You could try a later version of dbus-python.
Can you produce a glib version? It that does the same then at least it's
not a
PyQt problem.

I upgraded dbus-python to 0.80.2 (even rebuilt python, sip and pyqt4 from
scratch) with the same result.
A glib version of the same test application works as expected (as do more
complex glib-python-dbus apps).
I've also reviewed the package sources of my distribution's Qt4 and DBus
packages... No fancy patches or other magic there. The only thing I can
personally think of is that Qt4 is compiled with glib mainloop support
(which sort of works, I can use the dbus glib mainloop in PyQt4 apps, but
QCoreApplication.exec_() never quits).

test_glib.py:
from dbus.mainloop.glib import DBusGMainLoop
import dbus, sys, gobject
loop = gobject.MainLoop()
DBusGMainLoop(set_as_default = True)
print 'getting bus'; bus = dbus.SystemBus()
print 'getting obj'; obj = bus.get_object('org.bluez', '/org/bluez')
print 'done'
output:
getting bus
getting obj
done
