Randomly redirects

[eluser]tonanbarbarian[/eluser]
check your weblogs and see if that is the page it is really being redirected to, or it is something that firebug is doing
maybe even temporarily disable firebug and try to replicate the problem

if you are sure there is no code in your system that ever redirects to the logout page then maybe firebug is doing something silly

perhaps the page is partially being displayed and firebug is grabbing some of the text of the page, i.e. the logout link

try replicating the bug in other browsers

try installing the Live HTTP headers extension for firefox which records all request and you will be able to see exactly how the redirects are processing, what cookies are being passed back and forth etc
