This file seems to have changed from 3.5.4 to 3.6.

		this.prepare_submit = function(subjecttext, minchars)
		{
			this.textobj.value = this.get_editor_contents();

			return validatemessage(stripcode(this.textobj.value, true), subjecttext, minchars);
		}

cannot be found in this exact form, the closest I can find is

this.prepare_submit = function(subjecttext, minchars)
		{
			this.textobj.value = this.get_editor_contents();

			var returnvalue = validatemessage(stripcode(this.textobj.value, true), subjecttext, minchars);

			if (returnvalue)
			{

in the Prepare Form For Submit section.
