Yeah, that crash is called an "Artie Johnson" after the guy on the old Laugh In show who would topple over on his tricycle. Just about everyone does it at least once, and usually a couple times... don't sweat it.

I was just on the Cycle North Carolina tour two weeks ago, and was one of four trike riders among the 1050 participants. With a trike, you STAY CLIPPED IN when stopped. So each time a group of riders would come up to a stop and would need to pause for traffic you would hear click-click-click-clickity-click as everyone took one or two feet off the pedals. Than as soon as we began to start moving again, you could hear click-click-click-click-clickity-click again, as everyone snapped into their pedals.

Enjoy the clipless pedals, they really improve your connection to the bike and power to the pedal, as well as allow you to spin more effectively.
