It appears that having timezones on EXDATEs is preventing them from excluding occurrences.
The Icalendar data in the spec below contains an exdate for each normal occurrence of the event, so it should have no occurrences. I verified this interpretation by importing it into ical.app.
The data came from a calendar file which Paul sent which was causing a missing_method <=> on Hash. I fixed that problem, but in the process discovered this anomaly.

The initial assumption is that the time zones are causing the problem, I am currently investigating.
