Bug: Can't access Profile page

I'm not sure if this is an overall Listal issue or a Beta site issue, though I'm not able to access my Profile page either way, and haven't been able to for about a day now.

Not sure what happened but somehow you added a invalid item to your lists anyway I've fixed it.

Tom--Happened again. It seems to have happened when I tried to search for a person using the in-list search function. I'd copied the name from elsewhere, then pasted it into the search box, and the page gave me an error then, and now I can't get in again.

I've fixed the profile but which name was it and which list was it?
