Navigate to a screen containing the Project Explorer (i.e. open a file in a project).

Click the "cog" and select the "Repository View" and you get a NPE.

It is caused by ExplorerServiceHelper.getPathSegments() getting null from Paths.convert(path).getParent(). The "path" is uri='default://master@myteam/mortgages/', fileName='/'.

This probably relates to the "project == repository" changes.
