display command in /etc/mailcap needs quote escaping

[Waldir Pimenta]

I am not sure how, but apparently the line
  image/png; display png:'%s'; test=test -n "$DISPLAY"; priority=2
(line 22 of the usr/lib/mime/packages/imagemagick file in the deb package)
becomes:
  image/png; display 'png:'%s''; test=test -n "$DISPLAY"
in /etc/mailcap, as revealed by the command cat /etc/mailcap | grep "png".

The problem is the nested single quote symbols; the inner ones are not escaped so this results in a parsing error when running the command
  see image.png
which results in:
sh: 1: Syntax error: Unterminated quoted string
Warning: program returned non-zero exit code #2

Running "see" with the --debug option returns:
 - parsing parameter "image.png"
 - Reading mime.types file "/etc/mime.types"...
 - extension "png" maps to mime-type "image/png"
 - Reading mailcap file "/etc/mailcap"...
Processing file "image.png" of type "image/png" (encoding=none)...
 - checking mailcap entry "image/png; display 'png:'%s''; test=test -n "$DISPLAY""
 - program to execute: display 'png:'%s''
 - running test: test -n "$DISPLAY" (result=0=true)
 - executing: display 'png:'image.png'
sh: 1: Syntax error: Unterminated quoted string
Warning: program returned non-zero exit code #2

This is not exclusive of the png format; all the invocations of the display command in /etc/mailcap have the same problem.
