Comment 5 for bug 1223644

Please check your setups. OpenLP 2.0.2 is python 2 and LibreOffice 4 is Python 3. To use LibreOffice 4.x you need to be running OpenLP 2.x which is unstable at present

They should not be able to see each other as the packages are on different class paths.

From the error message you are invoking the new Python 3 uno module so how are you calling it from python 2.

This module has only been tested and supported on Python 3.
