I don't think anything could have fried on the sensor, as you can't actually reach the sensor from the front without passing through more optical filters.
I have to wonder if the sun could still be the culprit. The mirror will reduce the intensity, but as it isn't focused on the mirror itself that wont take the worst of the heat. If anything, perhaps a slight misfocus at the time would make the shutter a more likely target? If the sun were in perfect focus on the sensor, even the small distance to the shutter would give a defocus effect and may reduce the chances of it burning.
Given all this, I have to say I've shot directly at the sun with various lenses before without ill effect. I did try to keep the duration the sun was in view to a minimum though. Maybe a longer period is required.
