Here is the bug, I've just found it in Bugzilla and it has been marked as FIXED, so I'm probably right when saying that update has solved my friend's problem:

Can't understand why it's not shown in your application manager, are you sure you have activated the proper catalog? It is called Nokia System Software Updates (or similar, I'm translating from italian), with web address 'https://downloads.maemo.nokia.com/fremantle/ssu/mr0' (again, this is the italian catalog, don't know if it's the same for everyone).
