Impossible to create Cloze type question in Moodle 1.8 beta

At the moment it is not possible to create (or edit) a Cloze type question in Moodle 1.8 beta.

Upon entering question edit mode for this question (with debug mode on), error message displayed:
Notice: Undefined property: stdClass::$questiontext in C:\moodle\www\moodle18dev\moodle\question\type\multianswer\edit_multianswer_form.php on line 19

Upon saving question, this error message is displayed: "Neither a question id, nor a category id and question type, was specified."

I expect Tim has not yet fully implemented the new edit mechanism (with mm_forms) for this question type...
