Get "error -36" message when attempting to restore iPhoto library from Time Capsule.

I accidentally deleted my iPhoto library from my MacBook Pro. I have been backing up with Time Machine to a Time Capsule for quite a while so I figured all I needed to do was restore a copy from there. It's quite slow (trying to restore over wifi), but shortly after I give permission for my hard drive to be altered, I get an "error -36" saying that some files cannot be read or...something. Any ideas?
