A random problem I've noticed, want to see if it happens to anyone else.

I have minature display pics enabled in the contact list, but for some contacts it's just showing the standard icon, as if they have no display picture, but if i open a conversation window they do have a display picture (so it doesn't appear to be a problem communicating with the servers)

i've tried logging out and in again but it didn't change anything.

is anyone else experiencing this?
