bug#19745: 25.0.50; startup error

[Sam Steingold <sds@gnu.org>]

I am getting this error on startup now:

Debugger entered--Lisp error: (wrong-number-of-arguments format 0)
  format()
  apply(format nil)
  custom-save-all()
  customize-save-variable(package-selected-packages (vlf ensime edit-server))
  package-initialize()
  command-line()
  normal-top-level()

I just rebuilt emacs from scratch.
I wonder why is does customize-save-variable on startup...
