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")
[]

Does this happen every time?
