valgrind leak log

I have similar problems with 4.6 still.
I let xfdesktop run over night in valgrind, and memory consumption grew from 7% to 20%.

There were several messages on the console:
DBG[desktop-menu.c:353] _generate_menu(): menu file name is /etc/xdg/menus/xfce-applications.menu
Possibly caused by application updates, which are automatically done at night.
