This bug exists in Ubuntu 12.04.5 too. I was trying to port TortoiseHG to Caja (see https://bitbucket.org/nrbrtx/caja-thg) and got a problem in Ubuntu 12.04.
After adding MATE PPAs and installing caja-python and my script I have the following error on Caja start: (caja:13871): Caja-Python-WARNING **: g_module_open libpython failed: /usr/lib/i386-linux-gnu//libpython2.7.so.1.0: cannot open shared object file: No such file or directory ImportError: could not import gobject (error was: '/usr/lib/libpyglib-gi-2.0-python2.7.so.0: undefined symbol: _Py_ZeroStruct') Error in sys.excepthook: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/apport_python_hook.py", line 66, in apport_excepthook from apport.fileutils import likely_packaged, get_recent_crashes File "/usr/lib/python2.7/dist-packages/apport/__init__.py", line 1, in <module> from apport.report import Report File "/usr/lib/python2.7/dist-packages/apport/report.py", line 16, in <module> from xml.parsers.expat import ExpatError File "/usr/lib/python2.7/xml/parsers/expat.py", line 4, in <module> from pyexpat import * ImportError: /usr/lib/python2.7/lib-dynload/pyexpat.so: undefined symbol: _Py_ZeroStruct Original exception was: ImportError: could not import gobject (error was: '/usr/lib/libpyglib-gi-2.0-python2.7.so.0: undefined symbol: _Py_ZeroStruct') (caja:13871): Caja-Python-WARNING **: pygobject initialization failed (caja:13871): Caja-Python-WARNING **: caja_python_init_python failed As a temporary solution I made a symlink: sudo ln -s /usr/lib/libpython2.7.so.1.0 /usr/lib/i386-linux-gnu/libpython2.7.so.1.0 After that TortoiseHG Caja extension works on Ubuntu 12.04 as expected. Please fix this bug on Ubuntu or MATE PPA side. ** Also affects: python-caja (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1170017 Title: nautilus-python fails to load on 64-bit systems: g_module_open libpython failed: No such file or directory To manage notifications about this bug go to: https://bugs.launchpad.net/nautilus-compare/+bug/1170017/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
