The warning describes a problem with data generated internally, not a
problem with the user input. This is definitely a bug. It is not
necessarily a regression since it is conceivable that 2.12.3 just did
not diagnose the problematic situation. So it will require some
analysis by a developer to decide whether this is also a regression.
