What version is your icedtea-plugin package? The examples seem to work 
fine for me with IcedTea-Web 1.3 and 1.4 on Fedora. I don't know about 
Peppermint but you might still be stuck with 1.2, I believe that's what 
Ubuntu and Mint still have in their repos, since that's also what Debian 
Stable offers. Perhaps you could try with a newer release from Debian 
Testing or Debian Unstable?
