The short answer is Yes. I've read opinions on the forum about dirty interior contacts being a possible cause of malfunctions.
Never experienced the problem, myself, but I didn't have dust on my sensor for the first 5 years of camera ownership, either. So, when it happened, I gathered all the info I could, and cleaned the little bounder myself.
I figured if someone here had tried the self-cleaning route, I could be prepared in case the "Unthinkable" happens.
From the silence, I guess it must not be a common problem, or everyone takes their cameras to the neighborhood repair facility.
