Comment 7 for bug 709642

Same problem here (as described on some forum messages): unexpectedly logged out after pressing some keys which are not a shortcut (e.g. Alt Gr + Ctrl + Enter, possibly). I'm using pae kernel 2.6.35.28.36 but it happened before in the same way, if I remember correctly. I'm on an Asrock E350M1 motherboard with 4GB ram.
This is the relevant passage of syslog:
