  -----------------

  
  Release version: Ubuntu 16.04.3 LTS
  Package version: 3.18.2-1ubuntu4.1

  /usr/share/applications/evince-previewer.desktop comes from the evince
  package. It has an empty entry in mime types between application/x
  -ext-cb7 and application/oxps.

  ===8<===
  ...
  MimeType=application/pdf;application/x-bzpdf;application/x-gzpdf;application/x-xzpdf;application/x-ext-pdf;application/postscript;application/x-bzpostscript;application/x-gzpostscript;image/x-eps;image/x-bzeps;image/x-gzeps;application/x-ext-ps;application/x-ext-eps;application/x-dvi;application/x-bzdvi;application/x-gzdvi;application/x-ext-dvi;image/vnd.djvu;application/x-ext-djv;application/x-ext-djvu;image/tiff;application/x-cbr;application/x-cbz;application/x-cb7;application/x-ext-cbr;application/x-ext-cbz;application/x-ext-cb7;;application/oxps;application/vnd.ms-xpsdocument;
  ...
  ===>8===

  This entry gets included in /etc/mailcap via update-mime trigger from
  the package mime-support and the result is a broken line:

  ===8<===
  ...
  application/x-ext-cb7; evince-previewer %s; test=test -n "$DISPLAY"
  ; evince-previewer %s; test=test -n "$DISPLAY"
  application/oxps; evince-previewer %s; test=test -n "$DISPLAY"
  ...
  ===>8===

  Some programs that use /etc/mailcap get confused by the broken line so
  it would be nice if the typo it originates from was fixed.

  The expected result in /etc/mailcap from running update-mime:
  ===8<===
  ...
  application/x-ext-cb7; evince-previewer %s; test=test -n "$DISPLAY"
  application/oxps; evince-previewer %s; test=test -n "$DISPLAY"
  ...
  ===>8===
