Problem checking out a plugin from the WordPress SVN site?

Ever encountered the following error from svn when trying to checkout (or checkin) to a wordpress plugin repository:

svn: OPTIONS of ‘’: 200 OK (

Unfortunately, that error message makes almost no sense and is a bit frustrating, especially when you are in a hurry to get working on your repository…

After a bit of testing and trying various things, it turns out that the problem is that the WordPress SVN plugin developer instructions provide the incorrect protocol for the URL.  Rather than using ‘http‘, try using ‘https‘.  This should get you going again.
