Description

Hello,

when I open more than one form dialog on a layer with a Python init function, I have the following error message dialog box when I close the last form:

An error occured during execution of following code:
del _qgis_layer_parcelles20150504152756775

Traceback (most recent call last):
  File "", line 1, in 
NameError: name '_qgis_layer_parcelles20150504152756775' is not defined

Steps to reproduce it:
  • create a trivial Python init function (I use:
    def initFunc(dialog, layerid, featureid):
        pass
    
  • Set this Python init function in any Fields tab of layer properties.
  • Use the identify tool to open a form on a feature but do not close the form.
  • Use the identify tool to open another form on an another feature.
  • Close one of the two form dialogs (nothing happens).
  • Close the last form: error occurs !

I think this is related to #12676.

On QGIS 2.6.1, there is no error message.

Cheers !
