I'd like to use openoffice to programmatically convert docx to pdf. I know unoconv can do this, and indeed unoconv will do this for me, even if I run a separate listener (using unoconv -l) and invoke unoconv -n (so that it will die if it can't connect to the listener). Accordingly, I assume that my openoffice/pyuno environment is sane.
However, when I run an unoconv listener (or manually invoke openoffice as an acceptor), and try to connect with my own python code (derived from unoconv, and cross-checked with another openoffice library), the listener dies, and the uno bridge dies.
The error I get from the listener is:
terminate called after throwing an instance of 'com::sun::star::uno::RuntimeException'
The error I get on the python end is:
unoconv: RuntimeException during import phase:
Office probably died. Binary URP bridge disposed during call
I really have no idea how to go about diagnosing the problem here. Any suggestions as to the underlying cause or how to diagnose it would be greatly appreciated.
