Bug in pidgin

[nightwing.pidgin at mailnull.com]

I'm using the latest version of Pidgin, with Swedish translation on Windows 7 SP1 and I only got one problem:

I cannot /ban people on IRC. It simply returns me a message about that the command doesn't work under that protocol (Det kommandot funkar inte under detta protokoll).

Is there a fix for this? Kicking and all other commands work, but not /ban.

I'm using irc.uk.mibbit.net as my IRC server and I'm the channel owner
