You culd be right, Dan. I had similar problems when using PGP to sign email 
that was sent using the Opera email client. Opera has a 'feature' that 
concatenates email lines that end in a space character. This caused the 
message to be subtly changed and when PGP tried to verify the signed 
message, it reported that it had been tampered with.
