Fatal error: Cannot access empty property in...date_handler_field_multiple.inc...

I'm using PHP5. I went through a normal upgrade to Date/Calendar 2.0, went though update.php with the new modules off, got the usual CCK related errors, turned the new modules on, went through again update.php fine, no errors. Went through update.php again having read Karen's note. But when I went to a page with "upcoming events" blocks (one for one-time events, one for repeating events) and a mini-calendar block, I got:

Fatal error: Cannot access empty property in /home/ageofi2/public_html/sites/all/modules/date/date/date_handler_field_multiple.inc on line 127

I disabled the Calendar module, same error. I started disabling Date components and it seems Date Popup is the problem. I get the white screen with the above PHP error if Date Popup is on. I turned back on calendar and the rest, but NOT Date Popup and my page loads, but the mini-calendar has no events on it, and my upcoming events block is showing the titles but not the dates of the events. I am using only date fields that use the popup calendar date entry widgets.

I've appended exports of my "Event, One-time" node type and my Event, Repeating" node type. After that is an export of my "events_ongoing_upcoming" view that creates the block with upcoming events listed.
