dimension_browser example: cubes.errors.ConfigurationError

[KhaledTo]

When I'm trying to run application.py in examples/dimension_browser I get:

Traceback (most recent call last):
  File "application.py", line 105, in <module>
    app.register_blueprint(slicer, url_prefix="/slicer", config="slicer.ini")

 cubes.errors.ConfigurationError: config should be a ConfigParser instance, but is <class 'str'>

Looks like we need to pass an instance of ConfigParser. Anyone else is getting this error when trying this example in master branch?

Thought it was just a configuration issue on my hand, even though I was able to run it using slicer serve slicer.ini doing python3 application.py like in the example still fails. Looks related to issue #435

Closing as per #459 and #390.
