[DRE-maint] Bug#966653: gitlab: [BUG] Segmentation fault at 0x0000000000000000

[Antoine Le Gonidec]

I got bitten by the same crash during a system upgrade from Buster 10.4 to Buster 10.5, on a system using the Buster Fasttrack repositories.

Reverting the older versions of the following packages allowed me to avoid the crash:
- ruby-google-protobuf:amd64=3.11.4-5+fto10+1
- ruby-grpc:amd64=1.26.0-3+fto10+1

So the following command might help work around it for people that get this crash on a Debian Buster:
apt install ruby-google-protobuf:amd64=3.11.4-5+fto10+1 ruby-grpc:amd64=1.26.0-3+fto10+1

I use no instance of GitLab on Bullseye/Sid, so sadly I am not able to run tests in this context.
