Illegal string offset 'searchable'

[acfabro]

While DataTables is "ajaxing" data from the server (this specific instance happened in the admin section):

Which leads to this:

Here is the url of the http call: http://myserver/admin/user/data?draw=1&columns%5B0%5D%5Bdat…art=0&length=10&search%5Bvalue%5D=&search%5Bregex%5D=false&_=1452991348897

EDIT: BTW, this is a fresh install. No code has been edited yet.
