WTF is dbusmenu-qt ?

Since two days ago, kdelibs started requiring something called DBusMenuQt and the nightly builds were failing with

...
-----------------------------------------------------------------------------
-- The following REQUIRED packages could NOT be located on your system.

-----------------------------------------------------------------------------
   * DBusMenuQt  <git clone="" dbusmenu-qt.git="" dbusmenu="" git:="" gitorious.org="">
     API to import export QMenu instance using DBusMenu protocol
     dbusmenu-qt is a standalone library providing a way to import and export QMenu instances using the DBusMenu protocol.

I googled a bit, but did not find anything apart from some mentions in the sources of various projects. In the end asked at the kde-buildsystem mailing list and got a pointer to libdbusmenu-qt homepage (sort-of). So, if you're not really into checking out random revisions from repositories, the regular releases of libdbusmenu-qt are available at http://people.canonical.com/~agateau/dbusmenu/

 I added it to the kde-solaris project repository as well. It builds relatively smoothly, only requiring one patch for avoiding the __PRETTY_FUNCTION__ gcc extension.
