Same thing in sid. 4.13 version is available in git but not even
packages in experimental. I did try to run git master but got:
(xfce4-session:1832): Gtk-ERROR **: 11:53:25.090: GTK+ 2.x symbols
detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
Feb 11 10:18:23 ryzen5pc kernel: [ 4.070662] traps:
xfce4-session trap int3 ip:7f319df1b761 sp:7fff36a01dc0 error:0
Setting export GTK_PATH=/etc/gtk-3.0 before building did not help.
