There was a problem with the last merge :S

Somehow it didnt finished and didnt added some files under the svn control
(found thanks to lguillaume that reported some files were missing)

Last merge fixed and also merged modifications up to revision 15584.

I checked the diff
svn diff --new . --old https://svn.blender.org/svnroot/bf-blender/trunk/blender
And everything seems to be right now
