Taking a queue from Nick Thomas (Post), and as he so deftly notes. This breakage is also for SeaMonkey. To quote him (while replacing with the SeaMonkey Info [in bold])

You can check what you have by loading about:buildconfig, or evaluating navigator.buildID in the Error Console.
The solution is to download the latest Nightly build from http://ftp.mozilla.org/pub/mozilla.org/seamonkey/latest-comm-central-trunk.
Thank you Nick for calling out this issue!
