Apply diff2.txt from SF patch http://www.python.org/sf/566999 This patch enhances Python/import.c/find_module() so that unicode objects found in sys.path will be treated as legal directory names (The current code ignores anything that is not a str). The unicode name is converted to str using Py_FileSystemDefaultEncoding.
