User blog comment:Susanolivia/Tips to spruce up your main page/@comment-961279-20110118035545

Bug report: If the page you are linking to has a colon in it, you must paste in the full URL. Just listing the page will result in a link the web browser can't cope with. Example: http://phineasandferb.wikia.com/wiki/Rollercoaster:_The_Musical! instead of: Rollercoaster: The Musical!

I tried this with a gallery (Gallery:Rollercoaster) and got the same result, so the colon is throwing off in-wiki links.
