Account icons not showing up...?

jsamlarose

Greetings all... I've just noticed that two of my users' account icons aren't showing up. Their pictures are, and there's a space where their icons should be, but no picture. They're both using 32x32 icons hosted externally. Any suggestions? Icons turn up fine for other users that have entered something in the account icon field. I'm also noticing that those spaces are turning up (next to the username, where the icon sits) for some users that haven't actually entered anything in the account icon field... Weird...
