I've been doing some previous research about this error. There are some explanations here in StackOverflow related, the solutions suggested are quite unrelated though.
When I try to import Gtk from gi.repository, it crashes with the following output:
bash-4.2$ python3 Python 3.2 (r32:88445, Feb 21 2011, 21:11:06) [GCC 4.6.0 20110212 (Red Hat 4.6.0-0.7)] on linux2 Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import Gtk Traceback (most recent call last): File "", line 1, in File "/usr/lib64/python3.2/site-packages/gi/importer.py", line 76, in load_module dynamic_module._load() File "/usr/lib64/python3.2/site-packages/gi/module.py", line 251, in _load overrides_modules = __import__('gi.overrides', fromlist=[self._namespace]) File "/usr/lib64/python3.2/site-packages/gi/overrides/Gtk.py", line 400, in class MessageDialog(Gtk.MessageDialog, Dialog): File "/usr/lib64/python3.2/site-packages/gi/overrides/Gtk.py", line 404, in MessageDialog type=Gtk.MessageType.INFO, File "/usr/lib64/python3.2/site-packages/gi/module.py", line 127, in __getattr__ ascii_upper_trans = string.maketrans( AttributeError: 'module' object has no attribute 'maketrans'
Since this is an import straight from python console and not by executing a python file script I don't even have a clue how to handle this.
