The method I used which is admittedly more convoluted but worked, is:

  1. Fork the full Inkscape repository (so you have something like https://gitlab.com/you.name/inkscape) From the top right
  2. Create a branch based on the 1.4 branch from the + button > New Branch
  3. Base it on the existing 1.4 branch
  4. Name it something like Translations for your language
  5. Do the steps described in the wiki to replace the file .pot in your newly created Translations for your language branch
  6. Finally do the merge request from this private 1.4 branch of yours to the official 1.4 branch

  Hi all,
  I'm experiencing an issue when creating a merge request on the 1.4.x branch. I see this message "You can only create or edit files when you are on a branch" and the merge request is not created.
  I am following the steps in https://wiki.inkscape.org/wiki/index.php?title=Interface_translation#7._Make_a_merge_request 

  Is anyone else having this issue?

  Thank you, and kind regards,
