Comment 8 for bug 1103164

I want to add some details.

1) The bug reproduced with several PC with 64 bits kernel (different keyboards used)

2) The bug exists in kernels
Linux cd 3.8.0-030800rc4-generic #201301172335 SMP Fri Jan 18 04:45:42 UTC 2013 i686 i686 i686 GNU/Linux
and 3.9 version
but it happens much rarely with latest kernels.
