Comment 11 for bug 1249912

My bad: I should have stated that the excerpt from the log was from autosizer-2.0.0-beta.xpi attached above.

With SBA 2.0.3 no error in the console; I only mentioned it because the Assistant doesn't appear in this version as well (safe when manually launching chrome://autosizer/content/prefs.xul and clicking on its button).
