Update xdg gem
Version 2 of xdg
gem was released in 2012.
I found that there is a bug with it. When XDG_DATA_DIRS
is unset in the OS the wrong default value is used:
the basedir spec says the default value of /usr/local/share/:/usr/share/
should be used, but xdg 2.2.3
uses a different value instead of /usr/share
in some cases (see https://github.com/rubyworks/xdg/pull/8).
xdg
version of 4 doesn't have this bug so the upgrade of this gem resolves the issue above.
