Comment 2 for bug 1489154

Looks like only a few packages have been upgraded to 1.0.4, but not all:
- network-manager-gnome is 0.9.10.1
- libnm-gtk0 & libnm-gtk-common are 0.9.10.1
- gir1.2-nmgtk-1.0 is 0.9.10.1

as that upgrade is incomplete, the build should have been set to 'block-proposed'

To get the network working again, the solution is to downgrade to 0.9.10.1
