Spell Checker - Won't return to xinha - error on line 40

[guest]

I've been able to reproduce a bug in the Spell Checker that happens if you do the following:

Open the spell checker from xinha, Replace a misspelled word with nothing (as in delete the suggested replacement and have it remove the word). On clicking okay or cancel both IE and Firefox pop up an error.

Firebug for Firefox tells me uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER) [nsIDOMHTMLBodyElement.insertBefore]" nsresult: "0x80004003 (NS_ERROR_INVALID_POINTER)" location: "JS frame :: http://www.phatassproduction.ca/xinha/plugins/SpellChecker/spell-check-ui.js :: makeCleanDoc :: line 40" data: no] IE 6 and 7 just tell me it has an invalid pointer at line 40.

I've figured out this change fixes it just fine without altering any other function:
