That used to be the default guid value prior to Feb 12, 2007. 

http://svn.icculus.org/quake3/trunk/code/qcommon/md5.c?r1=1041&r2=1040&pathrev=1041

"unknown" was set as the guid when the client could not read the qkey file
(e.g. if qkey could not be created because of permissions problems).

With a modern build, the guid would just be a blank string in this case
just like a id q3 client with pb disabled.
