Arch Linux

Description:
When I try to use exo-open on a .desktop file, it opens in my text editor (Emacs in this case). I get the following warning:

$ exo-open GooglePlus.desktop

(exo-open:1288): exo-open-CRITICAL **: Launching desktop files is not supported when exo-open is compiled without GIO-Unix features.

This had been working up until fairly recently (perhaps until the most recent version, 0.10.1, submitted on 12-9-2012).

Additional info:
* package version(s)
* config and/or log files etc.


Steps to reproduce:

See above. My GooglePlus.desktop file is:

#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Name=Google+
Exec=/opt/google/chrome/google-chrome --app="https://plus.google.com/?hl=en"
Terminal=false
Icon=/home/jdarnold/.local/share/icons/hicolor/16x16/apps/chrome-https___plus.google.com__hl=en.png
Type=Application
Categories=Network;WebBrowser;

I don't use a DE, although I have "DE=xfce" in my .xinitrc.
