Problem with TV shows/actors, music artists etc.

I've noticed an odd bug today. Everytime I click a TV show, actor, director, author or music artist, I get a blank white screen with the text:

"A critical error has occured (IP address inside parentheses)

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

Has anyone else been running into this problem? I hope it could be fixed soon, it's really starting to bug me.
