1.3.6 broke the encoding of the job-sheets attribute.  Without the
fix included in 1.3.7 (or without downgrading to 1.3.5), banner pages
don't work.

The server enforcing valid banner pages just makes sure that we won't
break things in the future and that users know that the banner they
chose is not available.  This is not a bug, the "blindly ignore any
crap the client sends" in 1.3.6 and earlier was a bug.
