[PyKDE] PyQt dbus doesn't work with HAL

[Kovid Goyal]

Hi,

I've been testing dbus.mainloop.qt with HAL. With the glib mainloop my code 
receives HAL signals, with the Qt mainloop it does not. THis is with 
dbus-pythun-0.80rc3 and the latest PyQt4 snapshot.

Here's the test code
import dbus, sys
import dbus.mainloop.qt
from PyQt4.Qt import QApplication

def handle_signal(*args):
  print 'received signal:', args

dbus.mainloop.qt.DBusQtMainLoop(set_as_default=True)
bus = dbus.SystemBus()
bus.add_signal_receiver(handle_signal, None, None, None)

app = QApplication(sys.argv)
app.exec_()


The output I get is
QSocketNotifier: Can only be used with threads started with QThread
QSocketNotifier: Can only be used with threads started with QThread
received signal: (dbus.String(u':1.32'),)

But plugging in a USB device doesn't generate a signal. The same code with the 
glib mainloop does receive a signal.

Kovid.
