Scratch build with the fix:
https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=10955912

I have built rest-0.7.92-5.el7:
https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=10956119

Ah, we also need https://git.fedorahosted.org/cgit/virt-viewer.git/commit/?id=0443bd1 in virt-viewer.

moving to 7.4, it depends on missing patch in virt-viewer

That's bug 1374430, which has already been fixed.

Christophe Fergeau: should I test this bug with some special version of remote-viewer or library?

$ rpm -q rest virt-viewer spice-glib spice-gtk3
rest-0.8.0-1.el7.x86_64 -- this is a part of errata to be released.
virt-viewer-2.0-12.el7.x86_64
spice-glib-0.31-6.el7_3.2.x86_64
spice-gtk3-0.31-6.el7_3.2.x86_64

Strictly speaking, errata RHBA-2017:27064-01 https://errata.devel.redhat.com/advisory/27064 doesn't solve this bug.

I can reproduce this bug with new rest build from RHBA-2017:27064-01.

Yes, as the Depends on field suggests you need to have packages that were used to verify the bug 1374430 :)

This case is about a build time requirement (a new symbol in librest), not runtime - so upgrading just one component won't help
