It appears to be related to the *wired* network: with only the wireless network, sleep and hibernate work properly (as a matter of fact, it does not wake up properly from hibernate, but it might be related to another problem I have...).
With the wired network on, I still have the problem, and I can *not* disable the wired network manually: as soon as I try, the nm-applet freezes for a moment, then comes back with the network still on. Furthermore, from that moment, any sudo will freeze without asking for a password. Note that performing a sudo *before* trying to turn the network down (in order to "cache" the password) does not help: subsequent sudo will freeze as well. Hope this helps.
