XF 1.5 Issue when registering thru Facebook, Twitter


New users who registered using facebook or twitter have issues with the small avatars - the one on the user profile and on the recent posts in sidebar - they don't show up. please see image.

but the avatar appears on posts.

this issue happens only when registering thru facebook, twitter or google. everything is fine when going thru the regular email procedure.

i tried using the default theme and also disabled all addons but the issue persists. what could be causing this?
