Description Alexander Wigen 2016-11-24 08:38:55 UTC
Description of problem:

Trying to launch a VM with clipboard sync disabled causes a segfault.


Version-Release number of selected component (if applicable):

qemu-2.7.0-7.fc25.x86_64
spice-server-0.13.2-1.fc25.x86_64
spice-gtk3-devel-0.33-2.fc25.x86_64
spice-gtk3-0.33-2.fc25.x86_64
spice-glib-0.33-2.fc25.x86_64
spice-gtk-tools-0.33-2.fc25.x86_64
spice-protocol-0.12.12-1.fc25.noarch
spice-glib-devel-0.33-2.fc25.x86_64

How reproducible:

1. Setup a VM with spice graphics
2. Edit the VM xml and add to the  <graphics> section:
      <clipboard copypaste='no'/>
3. Attempt to launch the VM.

Actual results:

Comment 1 Christophe Fergeau 2016-11-24 12:23:22 UTC
This should be fixed in the upstream 0.13.3 release. This version is already built in rawhide, and I intend to push it to f25 too. In the mean time I've started a scratch build at http://koji.fedoraproject.org/koji/taskinfo?taskID=16596307 if you want to try it.

Hi Christophe,

Thanks the referenced build resolves the issue.

Cheers,
Alex
