Hi there Voidref,
Thanks for bringing this to our attention. The best way to tell us about listing errors, is by clicking the "More" button on the page, and then clicking "Report error"
Unfortunately, as I don't have a link to the property you're talking about, I can't file this for you. But if you go back to the page, filing the error on the page is the best way to fix this problem as soon as possible, both for you and for everyone on Trulia.
Thanks again for giving us a heads up on this!
