DBUS problems in new testing "image"

[Vasco Névoa]

Hello people.
I've been trying to get the latest "testing" version (that is linked  
in the community update) to work, but there seems to be something  
wrong with dbus.
With this new "image" (upgrade of stable through testing repo), some  
dbus operations fail:
- exposure.py does not launch (I can't get settings to show up);
- qpe will not open the modem (I have gsm muxer installed, and the  
dbus command to open a pts in "89qtopia" does not work);

>> dbus-send --system --print-reply --type=method_call  
>> --dest=org.pyneo.muxer /org/pyneo/Muxer  
>> org.freesmartphone.GSM.MUX.AllocChannel string:$identvar | grep  
>> string | awk -F '"' '{ print $2 }'
>> Error org.freedesktop.DBus.Error.NoReply: Message did not receive a  
>> reply (timeout by message bus)

My gsm muxer version is the latest (gsm0710muxd -  
0.9.2+gitr79e10fe8ad0828e5be9a5c087ac9ee04956674c1-r0.1)

Anyone has an explanation?
