 At the risk of boring the list to death  -- I do so because it's
 an error which may trip up other users, and annoys the hell out
 of people with signature only keys -- I want to nail this one down.

 I'm talking about a key 0x3E2056B9,  Owen Blacker <SIGNATURE KEY ONLY>.
 It appears to have an encryption part too, for CAST cypher.  
 One of us is doing it wrong, and I want to nail this problem down.


 Not least because I'm being accused of hacking, denial of service
 attacks, etc, behind my back and generally being called blind.  

 If "SIGNING ONLY" keys must carefully delete the encryption key,
 else PGP6 on Windoze will encrypt to their encryption part,
 then that is the problem and people who make such keys must
 be aware of, and fix, the problem.
