Yeah, the unix-specific code in glib for that is under 130 lines, even
smaller if you strip out checking for all the other dirs and just look
for desktop and templates.

Probably best just to copy and paste this where needed in xfdesktop
and/or thunar.  Not really worth adding to libxfce4util.  Should ifdef
for glib 2.14 and use the glib-provided functions instead.

Andrea, about the patch (xfdesktop at least):

No funnyCamelCasedVariables.  All lowercase, separate words by
underscores.  Read xfdesktop's HACKING file if you aren't sure.

No spaces between macro/function calls and the opening paren.  Again,

No need to check for NULL return on g_get_user_special_dir() when
checking for the desktop dir; glib falls back to returning ~/Desktop if
it fails to load a dir from the file.  (Note that this is only true
when checking for G_USER_DIRECTORY_DESKTOP; the others can return NULL).
