[mixcloud] Failed to parse JSON

[mbunkus]

• I've verified and I assure that I'm running youtube-dl 2017.08.13
• At least skimmed through the README, most notably the FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones
• Bug report (encountered problems with youtube-dl)

Downloading from Mixcloud fails with an exception in the JSON parser. Download works neither with valid login credentials nor without credentials.

There's currently no open issue related to "mixcloud" or "JSON" that matches my problem.

Here's the full output with --verbose directly after downloading 2017.08.13:
