[Spice-devel] [PATCH spice-server 0/1] prevent crash on video stream reattach

[Douglas Paul]

I experienced some crashes with qemu 3.1.0 compiled with libspice-server
0.14.0 on Gentoo. 

The problem reproduced reliably with a guest running Ubuntu 18.04.2 LTS.
If I connect a viewer at system startup, I would get a crash just after
the fade-in of the login prompt in GDM. 

Interestingly, I usually was unable to reproduce the issue if I waited
to connect until after the greeter was fully displayed.

The patch I used to correct the issue for me applies to the master
branch cleanly, so I suspect the problem may still exist.

The only other references to this issue I could find were two abrt
reports in CentOS:
https://bugs.centos.org/view.php?id=15171
https://bugs.centos.org/view.php?id=15441

I'm not sure if the agent->video_encoder is supposed to be guaranteed to
exist when this function is called. Please let me know if this is the
case and I can try to build my qemu with the newest git version of
libspice-server and reproduce the issue.
