Comment(by coling):

 Can I ask if 0.7 is actually released yet? It's not clear from
 http://www.freedesktop.org/wiki/Specifications/basedir-spec whether or not
 it's actually released yet as it is only available under a "latest
 version" link... which kinda implies it's going to be in the next version.

 Please note that any patch for this will also have to include support for
 falling back and checking the existing runtime dir such that new libpulses
 can connect to an older daemon (we actually currently support this with
 our even older pre-DoS safe version already, but IMO this older check can
 be dropped when support for XDG_RUNTIME_DIR is added - i.e a 2 slot FIFO
 ;))

 Please also note that the [http://standards.freedesktop.org/basedir-
 spec/latest/ar01s03.html spec] quite clearly states the properties of the
 directory (which align very closely to our own needs - no surprise seeing
 as Lennart helped pen the spec!) regarding user permissions, local
 filesystem etc:
  If $XDG_RUNTIME_DIR is not set applications should fall back to a
 replacement directory with similar capabilities and print a warning
 message.

 This is quite different from the requirements of XDG_CACHE_HOME. The
 [http://library.gnome.org/devel/glib/unstable/glib-Miscellaneous-Utility-
 Functions.html#g-get-user-runtime-dir Glib docs] state:
  On UNIX platforms this is determined using the mechanisms described in
 the XDG Base Directory Specification. This is the directory specified in
 the XDG_RUNTIME_DIR environment variable. In the case that this variable
 is not set, GLib will issue a warning message to stderr and return the
 value of g_get_user_cache_dir().

 (g_get_user_cache_dir() returns XDG_CACHE_HOME) This is clearly invalid
 and thus the glib implementation is very buggy (assuming the docs are
 correct).

 Are you (mccann) involved upstream? If so can you report this problem to
 them and paste a link here? If not, I will do this.
