Facebook: There was an error updating your profile picture. Please try again.

Easy fix: change the name of your picture.

Apparently some names are banned from facebook. Like this one: j0400967

I was trying to upload an image for one of the pages I am making on facebook. I tried converting the image to all different formats, including PNG, JPG, GIF, etc.. nothing worked. I even tried removing all the exif data. I tried using a photoshop filter to change the image, nada, no dice. Then I decided to change the image name. Bingo!

Name any image file j0400967 and watch the image upload choke. Fun.
