I added a historgram that looks like this:

  "CHECKERBOARD_SEVERITY": {
    "alert_emails": ["kgupta@mozilla.com"],
    "bug_numbers": [1238040],
    "expires_in_version": "55",
    "kind": "exponential",
    "high": "(1 << 31) - 1",
    "n_buckets": 50,
    "description": "Opaque measure of the severity of a checkerboard event"
  },

and I got the assertion failure in the bug summary.
Technically I also added two other histograms but I'm pretty sure it's the one above that caused the assertion. The other two have more normal-looking "high" values.
Reducing the high value to 1<<30 made the assertion go away.
