Bug#885864: This bug also affected evince.thumbnailer and probably /etc/mailcap

[Matt Roberds]

All,

This report is just for documentation; there is probably no action
needed on the part of the maintainers.

I have 3.22.1-3+deb9u1 installed on my system, and the evince.thumbnailer
file has the same double-semicolon problem in the same location as the
evince.desktop file originally reported.

I downloaded the source package for evince-3.26.0-2 and verified that
both evince.thumbnailer and evince.desktop have been fixed - the double
semicolon is gone from both - so that is OK.

However, I also wanted to note that the double semicolon was probably
also causing an incorrect entry in /etc/mailcap to be created when
evince was installed, which was causing another application (alpine) to
have trouble reading /etc/mailcap.

An excerpt of my /etc/mailcap follows:

---
application/vnd.comicbook+zip; evince %s; test=test -n "$DISPLAY"
application/x-ext-cb7; evince %s; test=test -n "$DISPLAY"
; evince %s; test=test -n "$DISPLAY"
application/oxps; evince %s; test=test -n "$DISPLAY"
application/vnd.ms-xpsdocument; evince %s; test=test -n "$DISPLAY"
---

alpine was looking for a mailcap entry that was further down in the
mailcap file, but it stopped searching when it hit the line starting
with "; evince".  It's probably alpine's baby to handle poorly-
formatted mailcap lines better, but it's also good to not put poorly-
formatted lines in mailcap.

Again, I am pretty sure the mailcap entries were generated from one of
the two files that were fixed, so future installs of evince should write
correctly-formatted lines to /etc/mailcap.

Thanks!
