Occasional Identified as a different user

var GLOBAL is occasionally being incorrectly populated (making "My Profile" link go to wrong profile)

Three times today while viewing another profile ( in this case coincidently both time while viewing apparent spammer @starcitizen ), the var GLOBAL is being populated with different user's profile info. In the first case it was @hellfroze I went to when clicking on "My Profile" then @islandtiffiney, and now @abeam.

This, btw, happened in Firefox 3.5b4 and in Safari 4 (I happened to be using a different browser when it happened the second and third time).

I am including entire contents of var GLOBAL from the view source while viewing @starcitizen's profile page while logged in as @skraggy:
