basestring does not exist anymore in Python 3: use six.string_types instead. In "try: .../except Exception as err: ...", err is a local variable, it does no more exist after the except block. Copy the exception in a new cls_error variable to fix Python 3 support. Extract of Python 3 documentation: "When an exception has been assigned using as target, it is cleared at the end of the except clause. (...) Exceptions are cleared because with the traceback attached to them, they form a reference cycle with the stack frame, keeping all locals in that frame alive until the next garbage collection occurs." http://docs.python.org/3.3/reference/compound_stmts.html#try Change-Id: I2efb14b3838f78d1ed5e09b3ccd4e796a3448aee
