They were made aware of it by a developer here over a month ago.
To sum it up:
- They are now aware of the problem.
- They're deploying a fix shortly.
- It might still cause issues with Chrome.
Seems like you'll just have to hang tight, sorry.
Here is their full official response:
Hi,
Thanks for posting, URIs are supported by the Skype Developer team and you can find out how to contact us by visiting the contact us page on http://developer.skype.com.
I can confirm that using Skype URIs on secure connections is presently broken. We have identified a fix and hope to deploy it shortly. Its likely, however, that the fix will still not work on newer versions of the chrome browser due to a change in the way it handles iframes launched over secure connections.

Update
7 months later and they still haven't properly fixed it.
However, that same thread now has a solution (of sorts) in its last comment:
Copy skype-ui.js to your project and replace below code to: this.SkypeClientDownloadUrl = this.httpProtocol + "//secure.skype.com/download"; this.assetPrefix = this.httpProtocol + "//secure.skypeassets.com/i/scom/images/skype-buttons/"; this.analyzeScript = this.httpProtocol + "//secure.skypeassets.com/i/scom/js/" + "skype-analytics.js";
Not pretty by any means, but at least it seems to work.
