PHP error in calendar display Undefined property: stdClass::$end

In response to lillyberger (@lillyberger):

I am using it for an ical feed. For one of my events, I am getting this error: Notice: Undefined property: stdClass::$end in …/plugins/simple-google-icalendar-widget/simple-google-icalendar-widget.php on line 169

It may be because the event is a holiday and has no end date?

Too bad I react so late, but I think you are right. I’m going to adjust the plugin so that if the end date is missing, the start date is copied over it.
I think you are already using another pluging, but thanks anyway for your comment.
