bug#21936: 25.1.50; Can't start eww: (args-out-of-range "" 0)

[Michael Heerdegen]

Hello,

when I call eww with any URL, I get

  error in process sentinel: Args out of range: "", 0

This happens with emacs -Q since a few days.

Here is a backtrace:

BTW, seems a similar error happens in other circumstances, too.


Thanks,
