           Summary: pulsemixer probe fails after device property is set
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: All
            Status: UNCONFIRMED

          Priority: Normal

Please describe the problem:
On the pulsemixer element, the property probe on the "device" property
functions correctly until the value of the "device" property is changed. Then
it always returns an empty list when the values are probed.

You do not even need the test case so verify this. It is obvious from the code
that the server property is being set when the device property is changed.

Steps to reproduce:
In a python shell:
>>> import gst
>>> pm = gst.element_factory_make("pulsemixer")
>>> pm.set_state(gst.STATE_READY)
>>> pm.probe_property_name("device")
>>> pm.probe_get_values_name("device")
['alsa_output.pci_10de_6a_sound_card_0_alsa_playback_0',
 'alsa_output.pci_10de_6a_sound_card_0_alsa_playback_0.monitor',
 'alsa_input.pci_10de_6a_sound_card_0_alsa_capture_0']
>>> pm.set_property("device", 'alsa_output.pci_10de_6a_sound_card_0_alsa_playback_0')
>>> pm.probe_property_name("device")
>>> pm.probe_get_values_name("device")
[]
