As long as there is an appropriate method for adding a legitimate entry to the chain, incorrectly entered data can be handled by appending corrected data on to the chain, and marking the error as such. Sensitive data, in this case, would be along the lines of "I accidentally added my private key instead of my public key." The action necessary here is the same as if I published my private key anywhere: stop using that key pair and generate a new one.
