Bug#952548: libfile-desktopentry-perl: fails to run xterm alternative when gnome is installed

[Patrick Zanon]

Package: libfile-desktopentry-perl
Version: 0.22-1
Severity: important

Dear Maintainer,

I prepared a script for opening P7M files which has been registered in a
.desktop file; this script runs in a terminal but when I call it with
the following command:

mimeopen some-file-name.P7M

the following error is shown:

Can't exec "xterm": File or directory does not exist at /usr/share/perl5/File/DesktopEntry.pm line 247.

The command fails because the xterm package is not installed, and 
the package should rather call "x-terminal-emulator" which has a
registered alternative in the gnome case; a direct call to xterm
requires a dependency to the xterm package which is not actually active.

Subsuming there are 2 solutions:

 1. calling "x-terminal-emulator" with one of its alternatives OR

 2. adding a dependency to the xterm pachage

Thanks in advance,
Pkzm
