I can reproduce this:
If i hold the LEFT-Cursor Key and press CTRL (LEFT+CTRL as in CTRL+c to copy) my Keyboard stops working. Mouse is still working.

"Meta-keyboard-commands" outside of X (e.g. CTRL+ALT+BACKSP or CTRL+ALT+F1...) are still effective, therefore i can restart X and log in again. So i think, this is somehow related to X.

I haven't found anything interesting in .xsession-errors or /var/log/Xorg.0.log but i have attached them. I logged the output of xev while provocing the freeze:

<code>KeyPress event, serial 31, synthetic NO, window 0x3c00002,
    root 0x5b, subw 0x0, time 30918556, (71,-8), root:(149,88),
    state 0x2010, keycode 100 (keysym 0xff51, Left), same_screen YES,
    XLookupString gives 0 bytes:
    XmbLookupString gives 0 bytes:
    XFilterEvent returns: False

FocusOut event, serial 31, synthetic NO, window 0x3c00002,
    mode NotifyGrab, detail NotifyAncestor
</code>
