@bone: Does this happen when you gear up, or down, or both? I noticed that, while gearing up, my boots occasionally touch the "helper" of the side stand (don't know the name of it). Mostly when i stand on the pegs, the rotation of my foot makes my boot touch the side stand. It is not enough to move it that much so the side-stand-switch turns off the bike, but maybe your switch/boot/anatomy is somewhat different ;o)
