early occurrence with dtstart leads to infinite program run

[icem]

This code in rails console leads to infinite program run in
occurrences method.

time = Time.parse("Fri Nov 19 18:00:00 UTC 2010").utc
event = RiCal.Event do
dtstart time
dtend time + 30.minutes
add_rrule "FREQ=YEARLY;BYMONTH=5;BYMONTHDAY=7;INTERVAL=2"
end
event.occurrences(:count => 3).map(&:start_time)

Also I've tried to run this test
https://github.com/rubyredrick/ri_cal/blob/master/spec/ri_cal/inf_l...
but with dtstart property changed from "DTSTART;VALUE=DATE:19400713"
to "DTSTART:19701018T000000" in VEVENT section(and DTEND property
too), and the result was the same (infinite run).

Is there is a way to avoid this bug?
ps. I'm using RiCal as a gem, version 0.8.7

I found some workaround on this issue. This bug occurs only in yearly recurrence type, and when dtstart doesn't equal to first rrule occurrence. So when I changed rrule to add_rrule "FREQ=YEARLY;BYMONTH=11;BYMONTHDAY=19;INTERVAL=2" it works correct. (Because dtstart set to Nov 19 2010)
