You are correct, Timofey. It seems to be related to a problem with VirtualBox, because:
* the problem IS reproducible - I have several tried to install both the "Gnome" Alpha 3 and the "LXDE" Alpha 3 of Lucid Lynx, and there was the same problem
* I have installed manually the version 3.1.4 of Sun VirtualBox and now everything works fine (until now).
