Narrative:

After landing, rolling out at idle, I braked to make an intersection turnoff to left. My left heel slipped off heel brake. Plane turned to the right and off runway coming to stop on dirt. The dirt was soft and aircraft stopped a bit quicker than on a hard surface and nosed over enough to catch the propeller. One blade turned through dirt, second blade stopped engine. Propeller bent, tailwheel bent at longeron when it came back down (after noseover) total damage assessment is in progress. I don't believe propeller would have been damaged if dirt surface was not softened due to rain in previous day(south).
