on Mint17: libreoffice .ods and .odt (and possibly others) do not get indexed. Logfile shows: :2:internfile/internfile.cpp:744:FileInterner::internfile: next_document error [filename.odt] application/vnd.sun.xml.writer :3:rcldb/rcldb.cpp:622:Db::add: docid 219334 updated [filename.odt|] similar messages for ods. Missing external application shows: python:libxml2/python:libxslt1 (application/vnd.openxmlformats-officedocument.wordprocessingml.document application/vnd.sun.xml however python-libxml2, python2-lxml and python-lxml are installed. How can this issue be resolved?

Did you try installing python-libxslt1 ?

This was the missing piece. Obviously the message was not clear enough for me. Also I had to figure out why the contents of .odt and .ods files still did not show up when updating the index from the GUI (running from terminal with recollindex -k was required). I will deal with the validity warnings in the terminal another time. Thank you for your prompt response.
