[SoaS] Collaboration in latest nightly Fedora Rawhide (soon-to-be F34) still broken

[Alex Perez]

Testing with the ISO downloaded from 
https://kojipkgs.fedoraproject.org/compose/rawhide/Fedora-Rawhide-20210123.n.0/compose/Spins/x86_64/iso/Fedora-SoaS-Live-x86_64-Rawhide-20210122.n.0.iso, 


I fired up two VMs with link-local networking to one another. They see 
the neighbors, but when you attempt to actually attempt collaboration, 
it fails with a traceback, "TypeError: section names must be strings"

This seems to have been encountered back in June of last year, and was 
fixed in issue #921: https://github.com/sugarlabs/sugar/pull/921. The 
actual merged patch is at 
https://github.com/sugarlabs/sugar/commit/58101044fc10ef2dc9e45f0998053bd3ec67e717.patch

and the link to the GitHub commit is here 
https://github.com/sugarlabs/sugar/commit/58101044fc10ef2dc9e45f0998053bd3ec67e717

Ibiam, we need to merge this one as well.
