Never seen that one before! Cheers for sending it over, I’ll get it looked into, as you’ve said it exists for /aboutus.aspx and not for the others in the old style.
The context @mike, because I know it’ll interest you (probably more than the fix itself being done,) is that the title wasn’t properly parsed. This issue had been fixed a while back, but this specific page hadn’t been recrawled of recent.
