It appears that so far very few people have taken the time to understand what it is Hidden is reporting. When I look at the log he sent along, I see him issuing one set of four bans. The mode messages that get sent out, however, are two sets, the first of 3 bans, all removed, and the second of 4 bans, all added--and the order is incorrect. If you mentally process the bans as he shows, you end up with 4 bans on the channel when in fact there is only one--the last one in his sequence. (You also see bans removed that weren't present in the first place.)
What he has reported is in fact a bug--ircu should not behave in this fashion. There's a slim chance that it is a bug in his client, but I would place the probability of that being the case at about 5-10%--no client I know of keeps track of the channel's ban list. My original question stands: What server version displays this behavior? -- Kevin L. Mitchell <[EMAIL PROTECTED]>
