Fix Missing Menus in FileZilla in Gnome 3.6 with Ubuntu 12.10

After doing a fresh install of 12.10 Quantal on my laptop and installing Gnome 3.6(my DE of choice) I noticed the File etc. menus wee missing from FileZilla and SVN Workbench.  After a bit of googling I found a solution that works for me.

Open a terminal and enter the following:

sudo su

then:

echo "export UBUNTU_MENUPROXY=0" > /etc/X11/Xsession.d/81ubuntumenuproxy

then:

exit

Now reboot and the menus should appear as normal.

NOTE: this solution will also disable global menus in unity if you wish to undo the change run the following:

sudo rm /etc/X11/Xsession.d/81ubuntumenuproxy

Enjoy Gnome 3.6 on Ubuntu 12.10
