Busted Steerer Tube

From Colin:

I recently bought a frame that came with a full carbon fork (my first fork with a carbon steer tube!) Just got done building it up, and on the test ride the handlebars felt wiggly, so I took out the fork and removed the warning sticker to find this nasty crack. The seller and I missed it because it was under the sticker but it was obvious while riding. Anyone have a fork with a steel steer tube?

Hmm... the seller missed it because it was under a sticker? You are more trusting than I.
