## Steps to reproduce

1. Launch GNOME Builder

2. Click on "Start New Project..."

3. Fill all required fields

## Expected result

The "Create Project" button gets enabled and you can click on it to create the project.

Example: https://builder.readthedocs.io/en/latest/_images/start-new-project.png

## Unexpected result

The "Create Project" button remains disabled, probably because the "Language" field does not display any language options to select, and selecting a language is required.

Example: https://luis-felipe.gitlab.io/media/2020/12/gnu-guix-gnome-builder-start-new-project-2020-12-16.png

Also, note that the "Select a Template" section does not show any templates. Although selecting a template is not required to start a project.

## System information

guix 08d8c2d

gnome-builder 3.36.1

## Additional information

I see the following output when I start gnome-builder from a terminal and follow the steps above:

$ gnome-builder

sh: getent: command not found

[PATCH] gnu: gnome-builder: Fix python and GI paths.

Recipients:(address . 45270@debbugs.gnu.org)(address . luis.felipe.la@protonmail.com)

Message-ID:20201218141616.31908-1-leo.prikler@student.tugraz.at

This patch fixes #45270 by patching PYTHON_PATH at application start time and

prepending "the correct" GI typelib paths at plugin load time.

* gnu/packages/gnome.scm (gnome-builder)[#:phases]: Add python-wrap and

patch-gi-repository-path.
