Comment 0 for bug 1716357

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;

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"
...
