Steps to Reproduce:
1. Run linux kernel in guest make it panic (no initrd cannot find root for example)
2. Connect spice client to the vm with the blinking keyb leds from the kernel panic
3. Switch to another window and try to type something, notice how every few ohter letters the letters change from caps to lowercase or vica versa.
I have a trivial workaround for that bug, just blocking modifier events when focus_out(). It could be done differently.
I'll post it on the mailing list for review.
Additionally, should we restore keyboard modifiers when going out of focus? I think we should, given that Spice currently offers a full remote desktop client which feels like a separate machine. However, if the remote windows would be managed by the client, and the root window hidden, then this behavior would be bad.
Marc's patch is now in upstream, commit:
84c0156 client inputs: stop blinking keyboard when out of focus
A new spice-client-0.7.2-1.el6 fixing this has been build, moving to modified.
Verified on spice-client-0.8.0-1.el6.x86_64.

For content author, I think users did not see this bug, but it was discovered during development.
Upon (linux) guest panic, a spice-client connected to the VM caused client's keyboard leds to blink and capslock to turn on/off continuously, in non-spice-client windows too.
Blocking keyboard modifier events when
spice-client windows is not in-focus.
That means when the user focuses out of spice-client window (focus on a different window), blinks stop blinking and caps-lock does not turn on/off.
