  As wine is pure userspace, it shouldn't make any harm to the system itself
(are You running it as a regular user, right?) 
  IMHO it's a gfx card lockup. It may happen because new wine uses more
sophisticated algorithms in the 3D rendering area, which may trigger various
bugs in the gfx card driver, thus freezing the card. This lockup makes the
X server to lock too, so even the keyboard gets dead.
  Is the machine connected to the net ? There are chances that the kernel
is still alive and that the remote access via ssh may succeed. You can then
kill the X server or at least reboot the system gracefully...
  I have one machine, where the same happens using firefox (native Linux
version). X server freezes including the keyboard, but remote access is working
and the system may be revived by killall -9 X. The machine is equipped with
Nvidia gfx card and Nvidia drivers. Other machine with the same card but
X drivers doesn't do this.
