It looks like, if an app-level exception is in progress, w_result may be None. Try checking for that before setting the flags. Also: did you mean to alter w_1's rbflags? Seems strange that you'd alter w_1 but not w_2. -- William Leslie Notice: Likely much of this email is, by the nature of copyright, covered under copyright law.
