Thank you so much! This is the real root cause of the problem. Your help 
let me jump straight into it. That method was added to the system by me 
on that date, but it shouldn't be there. Removing it fixes the issue.

Still. I also included your changeset, because it avoids iterating over 
each byte and calling #next, so it even with the root bug fixed, it 
helps as a performance improvement.

Thanks all for finding and investigating this problem!
