xdg-open doesn't use desktop file to open image/jpeg files

xdg-open is not using the appropriate desktop file to open files with mimetype image/jpeg. Here's what it should use in my installation:

paulo@monk:~$ xdg-mime query default image/jpeg
geeqie.desktop

and here's the relevant section from /usr/share/applications/geeqie.desktop:

paulo@monk:~$ grep -i exec /usr/share/applications/geeqie.desktop
Exec=geeqie -r %F

I confirmed that there was no local geeqie.desktop:

paulo@monk:~$ ls ~/.local/share/applications/ | grep geeqie.desktop
paulo@monk:~$

However, I can see xdg-open is opening image/jpeg files by running:

geeqie %F

because geeqie doesn't dettach itself from the terminal, and this is the message it shows on the terminal:

paulo@monk:~/foto$ xdg-open 1ª\ comunhã.jpg
Could not init LIRC support

I can also see that Thunar uses the correct desktop file: if I click on a jpeg file inside Thunar, geeqie is started and dettaches itself, and the upstart log confirms that the geeqie.desktop Exec line was indeed called:

paulo@monk:~$ grep -i geeqie ~/.cache/upstart/startxfce4.log
Remote Geeqie not running, starting...Could not init LIRC support
