Previously, this used to work; git bisect identifies cb4579ed6b ("Allow inserting parts of /dev/urandom with insert-file-contents", bug#18370) as the first bad commit. Other (non-stdin) pipes are also affected. Testing with a named pipe shows that the error only occurs after the pipe is first written to: # first terminal: mkfifo /tmp/fifo emacs -Q M-x insert-file /tmp/fifo # second terminal: { echo x; sleep 10; echo y; } > /tmp/fifo Before you run the command in the second terminal, you can observe that Emacs is just waiting for input from the pipe; as soon as you run the other command, Emacs shows the error before the sleep finishes.
