[Jamn42]

after installing docvert following issue #6 and get it done I got this on the log

✘ Images
✘Unable to run tests due to exception. Error in convertimages.py: No output data created. Command was "rsvg %s %s" which returned "(32512, 'sh: 1: rsvg: not found')"
✘ Lists
✘4. DocBook: Document contains 2 of the string "Return and indent for the next line gives correct result"
✘4. DocBook: Document contains 2 of the string "line continued for indent check that shows incorrectly..."
✘4. HTML: Document contains 2 of the string "Return and indent for the next line gives correct result"
✘4. HTML: Document contains 2 of the string "line continued for indent check that shows incorrectly..."

How can i solve this ?
