Description Dave Airlie 2013-05-28 01:21:25 UTC 
Originally reported wrongly, I've reproduced this problem.

No idea how to fix it.

We hit the assert in spice-server that was removed.

((null):3743): SpiceWorker-CRITICAL **: red_worker.c:9306:red_create_surface: Untested path stride >= 0

Alon any idea how we can avoid that?
Comment 1 Dave Airlie 2013-05-28 01:22:40 UTC 
to reproduce install F19 in a RHEL6.4 VM under not spice, then switch to spice.

The problem is I don't know of anything we can trigger to avoid using stride >= 0 cases

AFAIK there is no way to find out if the assert is there or not, so indeed there is nothing the guest can do to avoid it.

I believe this is best fixed on the RHEL side as the assert actually is a spice-server bug there. The RHEL side of this is being tracked in bug 952666

seeing this on x86_64 arch also.
Comment 4 Cole Robinson 2013-12-17 19:19:46 UTC 
RHEL6.5 has the fix, and sounds like the opinion is this can't be avoided guest side, so just closing as CANTFIX
