Comment 2 RHEL Program Management 2011-04-04 01:49:52 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 3 Christophe Fergeau 2011-05-30 16:29:01 UTC 
Is this bug still reproduceable with an up to date rhel6? The spice packages are now at 0.8. I tried to reproduce locally but haven't managed to do it so far. How do you achieve the connect/disconnect?

As far as I remember Junyi was able to reproduce it one time (see How reproducible - 1/15), It happened when Alon connected to the Junyi's machine remotely over WAN (from TLV to NAY).
So It is not easy reproducible one.
Comment 5 Lubos Kocman 2011-06-16 05:57:32 UTC 
QE is not able to reproduce it. Proposing to close bug.
Feel free to reopen this bug with up2date information.
