Can't install new plugins #3401
Description
Hi
We have a problem when is about to install a plugin from the admin interface of Etherpad.
When clicking on "Install" of any plugin, nothing happen in the web interface, but the log print out this:
[ERROR] console - SyntaxError: Unexpected token ...
at exports.runInThisContext (vm.js:53:16)
at Module._compile (module.js:373:25)
at Object.Module._extensions..js (module.js:416:10)
at Module.load (module.js:343:32)

at Module._compile (module.js:409:26)
at Object.Module._extensions..js (module.js:416:10)
Then Etherpad restart, and so on if we retry.
The log is the same with loglevel set at DEBUG.
We running node v4.9.1, npm v2.15.11 and Etherpad v1.6.5.
Version 1.6.6 is affected the same way.
