It may happen to other versions but I haven't tried yet. When using Libreoffice 1:4.1.1-0ubuntu1~precise1 (Help - About LibreOffice shows Version: 4.1.1.2, Build ID: 410m0(Build:2) installed using the PPA libreoffice-4.1: when adding the attached extension it shows an error message such as: ------------- <type 'exceptions.AttributeError'>: 'exceptions.ImportError' object has no attribute 'with_traceback', traceback follows /usr/lib/python2.7/dist-packages/uno.py:334 in function _uno_import() ["%s (or '%s.%s' is unknown)" % (py_import_exc, name, x)] /usr/lib/python2.7/copy.py:60 in function <module>() [from org.python.core import PyStringMap] /usr/lib/python2.7/dist-packages/uno.py:268 in function _uno_import() [return _g_delegatee( name, *optargs, **kwargs )] /usr/lib/python2.7/decimal.py:139 in function <module>() [import copy as _copy] /usr/lib/python2.7/dist-packages/uno.py:268 in function _uno_import() [return _g_delegatee( name, *optargs, **kwargs )] /usr/lib/python2.7/dist-packages/simplejson/__init__.py:109 in function <module>() [from decimal import Decimal] /usr/lib/python2.7/dist-packages/uno.py:268 in function _uno_import() [return _g_delegatee( name, *optargs, **kwargs )] /home/carles/.config/libreoffice/4/user/uno_packages/cache/uno_packages/lumd3lp.tmp_/Mendeley-1.10-dev3.oxt/Scripts/MendeleyDesktopAPI.py:17 in function <module>() [try: import simplejson as json] /usr/lib/libreoffice/program/pythonloader.py:103 in function getModuleFromUrl() [exec(codeobject, mod.__dict__)] /usr/lib/libreoffice/program/pythonloader.py:149 in function writeRegistryInfo() [mod = self.getModuleFromUrl( locationUrl )] ------------- Using Libreoffice 4.1 from libreoffice.org: works correctly. Editing the extension with this change: -except ImportError: import json +except: import json (it appears twice) Then it works correctly - not sure why. Let me know if you need some more information.
