[Qgis-developer] Problem with empty Postgis views

I have QGIS projects that load Postgis views that are sometimes empty,
sometimes contain data.
I noticed that current master cannot load empty Postgis views anymore.
The error message is that "PostgreSQL layer has no primary key". Note
that I did select a primary key manually.
Same issue if you load the view using "Add Postgis layer" or if you load
an existing project that has a reference to the empty Postgis view. I
checked the <datasource/> in the .qgs file and the primary key is
present in the datasource element.
So, there seems to be an issue that current master cannot load empty
Postgis views. It is a regression, as this used to work in previous
Note that the reason why my view is sometimes empty is that it contains
objects filtered by status "projected" - there can be dates when there
are no elements with such a status.
I hope this can be fixed before we ship QGIS 2.12.
