Comment 2 for bug 118936

In my case:

-create a dummy user.

-log in with that user.

-open Alacarte.

-uncheck the "show" checkbox for Rhythmbox.

-right-click the Totem launcher and delete it.

-hit "revert".

The RB show checkbox becomes checked again, but the Totem launcher is nowhere to be seen. This procedure can be tested with any additional program; uninstalling and then reinstalling it won't recover the launcher. The user -me- has to manually create the launcher, and if he uninstalls the software the laucher stays there until he manually hides / deletes it.

Happens in my PC, at least.
