Uzbl

I have been using uzbl-browser on Arch Linux. All was fine through the 2010-01-05-1 version. After upgrading to 2010-02-02-1, uzbl-browser seems to be broken. It recognizes no keyboard input. Mouse input works but not keyboard input of any kind.

When starting uzbl-browser from the terminal I get an exception ReferenceError:

I have upgraded uzbl on 2 Arch Linux machines and it is broken on both. I have another Arch machine on which I upgraded the entire system but NOT uzbl and uzbl (2010-01-05-1) still works fine on that one so the problem seems to be with uzbl and not some other conflicting program.
