In QGIS 2.5 the problem is different. Opening and editing a new feature
form with openFeatureform(temp_feature) automatically adds it to the layer,
and does not update the temp_feature attributes after you press ok.

I believe that the original behavior were to update the temp_feature
attributes and then you would need to manually add the feature to the layer
with layer.addFeature(temp_feature), this would allow some feature
manipulation between the processes.
