Haha, wubbly. Happened when I edited the Feedback page to remove the Business address I was forced to add. Perhaps because of the emoticons on the feedback form.
It isn't worth fixing. Composr's defaults prefix and suffix emoticons with :, but users do not always have to do that when they add their own. This means there could be "gotchas" involved in checking for emoticon exceptions. It can also get complicated when dealing with third-party forum drivers and their emoticons.
I'll make a note on the maintenance status page about this.
But for real, how did this occur? I noticed there is an emoticon called wub; were you trying to add that on the page?
