Bug report: Event title missing in predictable pattern

Here’s an interesting bug. I’ll describe how I got it.

I got this with both 2.1.3 and 2.1.4.

My feed used the Event Builder as follows:
[if-not-all-day] [start-time] [/if-not-all-day] <span class="gce-list-event"> [event-title] </span>

Feed settings:
Expand recurring events? Yes
Date format: l, M j
Time format: g:ia
Cache duration: blank
display mode: grid
number of events per page: 9 events
display staft date offset: 0 days ahead
minimum feed start date: 1 months back
maximum feed end date: 2 years forward

The code in the page:
[gcal id="1292" display="grouped-list"]

The first event that got displayed happened to be an all-day event.

The weird result: the first event listed didn’t have a date associated with it! (Other all-day events were fine.)

The problem can be solved in two ways — by giving the first event to get pulled from the calendar a start time, or by changing the code in the page to the following:
[gcal id="1292" display="grouped-list" interval="days" interval_count="8"]

Note that the following does not solve the problem:
[gcal id="1292" display="grouped-list" interval="events" interval_count="8"]
