1) Add a shapefile
2) Go into its style properties
3) Change to "Graduated" symbol.
4) Press "Classify".
You'll now get an error:
"Renderer creation has failed"
This is almost certainly because a column to classify against wasn't specified. However the error should be a user friendly one:
"Please select a Column to classify."
Alternately, just add "no value", which is what happens when this is done with "categorised" style type.
