Bug#909681: gnome-builder: git plugin not working in a submodule

[Jérémy Lal]

Package: gnome-builder
Version: 3.30.1-2
Severity: normal

Typically, project A tracked by git, has submodule A/B/ tracked by another git repo as well,
setup by `git submodule update --init --recursive` or similar.

Note that A/B/.git is a file containing `gitdir: ../.git/modules/B`.

In this case, when opening the submodule as a project, the git plugin does not work at all.

The bug might be in libgit2, or even libgit2-glib.

Jérémy.
