Okay, I filed a bug with Fedora to see if they can update what they ship.

Well, I do have a bit list of nodes on my system right now.  It looks 
like what he says happens does happen.  I have worst_qual set to 100 and 
I do see a handful of nodes with quality just below 100, some as low as 
94, but none too far below 100.   I'll uninstall the Fedora libax25 and 
put in the latest, see if it's any different.
