Bug#964877: xdg-email: open_generic code path doesn't handle Terminal=true

[Simon McVittie]

Package: xdg-utils
Version: 1.1.3-2
Severity: normal
Tags: upstream

Steps to reproduce:

* Be in LXQT, Enlightenment, or any desktop environment that does not
  match one of xdg-email's special cases (I used lxqt-core)
* Install a graphical MUA (I used balsa)
* Install a text-mode MUA that has a .desktop file (I used mutt)
* Set balsa as the default MUA. In a throwaway test environment, you can do
  this with:
  mkdir ~/.config
  (echo "[Default Applications]"; echo x-scheme-handler/mailto=balsa-mailto-handler.desktop) > ~/.config/mimeapps.list
  (or in a non-throwaway environment you'll want to edit the file with a
  text editor to preserve existing configuration).
* Alt+F2, xdg-email me at example.com
  (or the desktop's "run a command" functionality, whatever that is: Alt+F2
  is correct for at least GNOME and LXQT)
* If balsa launches, exit from it
* Set mutt as the default MUA, for example:
  (echo "[Default Applications]"; echo x-scheme-handler/mailto=mutt.desktop) > ~/.config/mimeapps.list
* Alt+F2, xdg-email me at example.com
* In a terminal emulator, xdg-email me at example.com

Expected result:

(This is what will happen if you use a GNOME-derived desktop or XFCE,
instead of LXQT.)

* After first "xdg-email", balsa appears. After completing the setup wizard
  if necessary, there is a new blank draft email to me at example.com.
* After second "xdg-email", a terminal emulator appears, with a new blank
  email to me at example.com opened in mutt
* After third "xdg-email", another terminal emulator appears, again with a
  new blank email to me at example.com opened in mutt

Actual result:

* After first "xdg-email", balsa appears as expected.
* After second "xdg-email", nothing happens.
* After third "xdg-email", mutt runs in the terminal emulator from which
  you ran xdg-email.

Workaround:

* Install xterm (workaround for #773915)
* Ensure you have libglib2.0-bin installed
* Run: XDG_CURRENT_DESKTOP=GNOME xdg-email me at example.com
