[evolution-patches] patch for #41579

[Rodrigo Moya <rodrigo ximian com>]

I can't replicate the bug, since the calendar file loads correctly both
in local and connector calendars. Also, double clicking on it opens up
the editor correctly, with no crashes.

So, I can't track down why there's a NULL property, thus this fix only
makes sure we don't try to add the NULL property.
