Confirming that I see this with kmail 1.9.5 (kde 3.5.5).

It is caused when there is no unique-uid field in the (invalid) UIDL response:

  uidl
  +OK 224 messages
  ...
  212 <0660472257.20070510230429 gpreeves com>
  213
  214 <209l452f.3417037 fonterra com>
  ...

Deleting the single message with no unique-uid, corrected the problem.

I don't have control of my pop server, but it appears to generate unique-ids from message-id headers.  The problem message had the following header:

  Message-ID: 20070511113407190 www aa co nz

Note the missing <> which confused the pop server.

If anyone else hits this issue, the following commands may be helpful.

openssl s_client -host pop3_host -port 995

+OK POP3 server ready.
user your_username
+OK please send PASS command
pass your_password
+OK your_username is welcome here
uidl
