Forked repository is inaccessible (404) and so is merge request (500)
Tried to fork a repo, stuck on the importing page, the following day the repo page gives 404 and a related merge request gives 500.
Steps to reproduce
Try to fork a repo and in some cases, it may hang.
What is the current bug behavior?
I created a fork of https://gitlab.gnome.org/GNOME/glib repository. It hung on "importing repo" page, but the repo itself was accessible, so I didn't pay much attention. Today, the forked repo gives 404 error (https://gitlab.gnome.org/nightuser/glib) and a related merge request (GNOME/glib!1198 (closed)) says about an internal server error.
What is the expected correct behavior?
The repo is forked correctly.
