• create a PostGIS DB
• create a simple geometric table
• DB Manager > Table > Verioning
• add the view to the canvas
• start editing
• insert a feature
• Commit errors:

ERROR: 1 feature(s) not added.
Provider errors:
PostGIS error while adding features: ERRORE:  non è possibile eseguire INSERT RETURNING sulla relazione "version_current" 
NOTA: È necessaria una regola ON INSERT DO INSTEAD non condizionale con una clausola RETURNING.

Which translates approx to:

ERROR: cannot perform
INSERT RETURNING on relation "version_current" 
HINT: You need an unconditional ON INSERT DO INSTEAD rule with a
RETURNING clause.

The same operation on the same view works smoothly on QGIS 2.14.
