Can somebody please review this patch: https://sourceforge.net/support/tracker.php?aid=1692335 It aims to fix the pickling of exceptions whose __init__ methods don't call Exception.__init__ at all, or with a different number of arguments. This should be fixed before 2.5.2. Georg -- Thus spake the Lord: Thou shalt indent with four spaces. No more, no less. Four shall be the number of spaces thou shalt indent, and the number of thy indenting shall be four. Eight shalt thou not indent, nor either indent thou two, excepting that thou then proceed to four. Tabs are right out.
