I have installed SimpleTest, applied patch to core, and it fails its own test

I just installed simpleTest on my development drupal copy. After applying the patch to core and turning the module on, I ran the test on Simple Test module itself. I got an error message:

Notice: Undefined index: description in simpletest_test_form() (line 36 of C:\Documents and Settings\pathToDrupalSite\sites\all\modules\simpletest\simpletest.pages.inc).

Is this to be expected? (I don't really thing so.)

Anyone knows what went wrong and what can I do to fix it?

Am I using simpletest-6.x-2.10.
