 Briefly about my case:
 I created a python plugin,
 and it creates QgsVectorLayer's from Postgis database.
 I do add qml styles to my layers, with layer.loadNamedStyle(path_to_qml).
 And in qml i've specified form init functions in python
 <editforminit>myInitMethod</editforminit>
 I'm trying to initilize some data fields with editforminit function.

 The problem:[[BR]]

 1) i add a layer with my plugin


 2) select the added layer which has <editforminit> specified


 3) toggle the layer to edit mode


 4) try to add a layer object to map, click on the map


 5) then qgis always craches

 Problem is only when i have set editforminit function.

 [[BR]]



 but if i do
 steps


 * (save project)


 * (close and open qgis)


 before adding new object to my layer, then editforminit function is
 invoked and everything works.


 Maybe there's a workaround?
 Maybe some refreshing?

 I do after adding layers:


 self.iface.refreshLegend(myLayer)


 self.iface.mapCanvas().refresh()
