warning: stream_select() expects at least 4 parameters

Hi,

I'm getting the following error everytime i'm on the "edit" page of a node:
warning: stream_select() expects at least 4 parameters, 1 given in /home/six/public_html/includes/theme.inc on line 597.

Is anybody aware of this bug? I've tried disabling all additional modules and gone through a clean install & the error seems to kick in after I try uploading an image with the FileField module (which imagecache then grabs). Weirdly the error remains even when all the modules are disabled.

Ideas?

Tom
