Ok. the updated packages are everything kde, gdb, sip, pyqt (there's also a 
crash of printer-applet when starting kde, but it's not influencing the happy 
reset fest), module-init-tools, openal, sdparm, texlive-bin, and today 
kdebase-* and qt 4.5.3-2 ->4.5.3-3. Here's the  message in .xsession-errors:
Warning: Only changing the first 3 of 32 buttons.

The line "touchscreen" made me think about my touchscreen screen, but I 
unplugged its usb cable, and nothing changed. I'm running with no xorg.conf. 
Xorg.0.log says something about my WinTV's IR input device, even if I don't 
have such a IR device, being recognized as keyboard. So, I got off the wintv 
card, but nothing changed. Dmesg says this, at the very end:

mtrr is new, I think is something about the default drivers for the videocard. 
But the other trace is not a news, and never caused problems. Tried to swap 
keyboard, but to no avail. My other Ubuntu partition runs fine. In order to 
replicate the bug, it's enough to try to login in GMail. Pressing Enter = 
reset.
Ciao!
