Hello François,
I just tried to reproduce this crash, without being involved
in packaging qemu.
But could not get my VM to crash - it shows just the video,
either with spicy or the virt-manager integrated viewer.
Therefore could you please add the exact VM config? (virsh dumpxml)
This gstreamer warning is from /var/log/libvirt/qemu/VM.log ?
Have you specified a special video out to mplayer?
Or is there also a driver to be installed or guest tools?
How could one see if "streaming" works?
Or maybe you could record a backtrace on your system with something
like this (replace <PID> with the pid of the right qemu instance):
script -a gdb_qemu-system-x86_64_$(date +%Y-%m-%d_%H-%M-%S).log -c "gdb -q
--pid <PID> -ex 'set width 0' -ex 'set pagination off' -ex 'cont' -ex 'bt'
-ex 'detach' -ex 'quit'"
Kind regards,
Bernhard
