Very odd, while dissecting a progressing error, it ended up revealing something broken with python and OGR provider layer with OSM datasets (I must assume other types also impacted).

Steps to reproduce
  1. Create a new project
  2. Add the attached test.osm dataset (add the line multipolygon layer)
  3. Make sure that added layer is selected in the layers panel
  4. Open the python console
  5. Type the following
    (not iface.activeLayer())
  6. Notice python throwing the following error
    Traceback (most recent call last):
      File "/usr/lib/python3.6/code.py", line 91, in runcode
        exec(code, self.locals)
      File "<input>", line 1, in <module>
    SystemError: error return without exception set

This triggers processing errors with vector features parameters.
