This bug was fixed in the package cups-filters - 1.8.3-2ubuntu1

---------------
cups-filters (1.8.3-2ubuntu1) xenial; urgency=medium

  * Merge from Debian unstable.  Remaining changes:
     - Added the binary packages cups-filters-lsb and cups-filters-invalid-mta
       to temporarily replace the dropped LSB support in Debian/Ubuntu which
       we need for distribution-independent printer driver packages. This
       will be removed as soon as a new concept for distribution-independent
       printer driver packages is in place.
     - Added build dependency on python3-all-dev for the cups-filters-lsb
       binary package.

cups-filters (1.8.3-2) unstable; urgency=medium

  [ Till Kamppeter ]
  * Install the new /usr/share/cups/mime/cupsfilters-ghostscript.convs file

cups-filters (1.8.3-1) unstable; urgency=medium

  * New upstream release
   - cups-browsed: When creating or modifying a local print queue
     set the printer-is-shared bit to false in a separate IPP
     request as this operation errors on queues directly pointing
     to remote CUPS queues with the IPP backend. This way we can
     ignore the error and assure that all other settings are
     applied (LP: #1560099)

  * Refresh debian/copyright to reflect the gstoraster convs file split

cups-filters (1.8.2-3) unstable; urgency=medium

  * Bump Standards-Version to 3.9.7 without changes needed
  * Drop superfluous liblouis-data dependency (Closes: #816304)
