Sorin Marian Nasoi has proposed merging lp:~zorba-coders/zorba/fix_html_module 
into lp:zorba/data-converters-module.

Requested reviews:
  Matthias Brantner (matthias-brantner)
  Sorin Marian Nasoi (sorin.marian.nasoi)

For more details, see:
https://code.launchpad.net/~zorba-coders/zorba/fix_html_module/+merge/106814

When the tidying is not successful, an error is raised instead of just 
returning the empty sequence.
