Comment #2 on issue 26 by funchords: 3.6.1 client "Protocol Error" additional information contains unreadable characters
http://code.google.com/p/ndt/issues/detail?id=26

I have now seen this on the M-Lab-hosted client (not through the FCC)

Note, the ### above actually was a square character, like a font sometimes gives when
it doesn't have a translation for a character. It would not cut and paste.

I also had the Java console open during this run. Here is what was captured:
