Since the stabilization of x11-drivers/xf86-video-qxl 0.1.1, Xspice segfault at startup because it use the new API to add memslot.

Step to reproduce:

1) USE=xspice emerge -1 =11-drivers/xf86-video-qxl-0.1.1
2) start GDM or Xspice script
3) Get the segfault

To prevent this segfault we need to use a patch from the future spice 0.12.5 release.

Upstream fixes:
http://cgit.freedesktop.org/spice/spice/commit/?id=1d18b7e98ab268c755933061d77ccc7a981815e2

I have worked on this issue with upstream guys and running spice 0.12.4 with the attached patch works well.

spice 0.12.5 is released. It include the fix that cause the Xorg segfault with xf86-video-qxl-0.1.1.

We need to bump to 0.12.5 and remove older releases (or include the patch attached)

[Comment 2 Matthias Maier 2015-08-14 04:22:02 UTC]

0.12.5 is stable for a long time now.
