This is a symptom of "Too easy to activate the proposed repository"

However, those error reports should not be disregarded in error
tracker statistics. If some proportion of Ubuntu users turn on
- -proposed when they shouldn't, that is a real influence on the average
reliability of Ubuntu as people actually experience it.

In the design linked from that bug report, I replaced the checkboxes
with a menu containing three or four options:
* "All updates" (the default, -security + -updates + -backports)
* "Security and recommended updates" (-security + -updates)
* "Security updates only" (-security)
* "Custom" if current config is anything else, e.g. with -proposed.

This would also make it much harder for people to make mistakes like
having -backports turned on but -security turned off.

You could implement this change independently from the rest of the design.

I have a design for making that easier, too. :-)
