Comment 4 for bug 798951

This bug does not affect upgrades from the Gnome 3 PPA, just new installs. This is what my working upgrade shows:

/etc/xdg/menus$ ls -l
-rw-r--r-- 1 root root 7433 2011-04-06 08:15 applications.menu
drwxr-xr-x 2 root root 4096 2011-04-29 07:03 applications-merged
-rw-r--r-- 1 root root 7381 2011-06-01 05:51 gnome-applications.menu
-rw-r--r-- 1 root root 2803 2011-04-09 09:44 gnomecc.menu
-rw-r--r-- 1 root root 488 2010-06-07 00:20 gnome-screensavers.menu
-rw-r--r-- 1 root root 10920 2010-12-23 11:53 kde4-applications.menu
-rw-r--r-- 1 root root 279 2008-01-04 18:54 kde-information.menu
-rw-r--r-- 1 root root 1347 2011-03-07 11:23 settings.menu
-rw-r--r-- 1 root root 3891 2011-05-26 09:46 unity-place-applications.menu

applications-merged comes from Wine. applications.menu and settings.menu are not present on a new install.
