Error When Viewing People/Artist Profiles

When clicking from a search or from item entries, some people give the following error

A critical error has occured (70.83.82.135)

This error has been logged and will be dealt with asap.

So far, I've encountered it on the following people":
www.listal.com/artist/katharine-mcphee
www.listal.com/artist/jc-chasez
www.listal.com/person/john-barrowman

The same error page shows up when deleting images (though the image does delete)

Thanks, Tom :)

And I was just trying to delete an image that had been uploaded twice by accident. I can't remember where it was now, but if it happens again I'll post with the link.

Just an update on the deleting error, I've noticed that only seems to happen in Firefox.

www.listal.com/person/adrianne-palicki/pictures

That page gives me the error when I delete a photo.
