"missing whitespace before attribute" is an error message generated in 
xmlreader/source/xmlreader.cxx, so it smells like your setup is such 
that it erroneously declares the oovbaapi.rdb as a services rdb (which 
are in XML format today) rather than a types rdb (which are in binary 
format).

What also looks odd is that your setup apparently mixes 
libreoffice-4.0/lib/libreoffice/program/uno.py and 
libreoffice-4.2/lib/libreoffice/program/types/oovbaapi.rdb.

What I noticed is that libreconverter's loutils.py has two bugs, one is 
a missing comma that made it completely nonfunctional at least for me 
and is fixed with 
<https://github.com/colonelqubit/libreconverter/commit/7e0f81ac96106ccb4baff4951126885841b1e887> 
"Merge pull request #1 from stbergmann/master" now.

The other is that it hardcodes the location of the LO installation as 
/usr/lib/libreoffice/program in the _lopaths variable.  You presumably 
do have a LO installation there, but it likely doesn't match the LO 
installation from which you take the python executable to run 
libreconverter.py with.

What worked for me, trying it out with a local LO 4.2 build, is to patch 
loutils.py like

to match the LO installation of the python executable used when running 
libreconverter.py,
