    screensaver-proxy: Fix crash when client vanishes
    
    We were using the "sender" variable, which was gathered from the
    hash table, instead of using directly the argument passed to the
    function. As the sender variable was freed pretty much straight
    after it was removed from the cookies hashtable, we were accessing
    freed memory, usually leading to a crash.
