The workaround is to use:

  echo -ne "ignorethis\n" | svn ps svn:ignore -F - .

It's possible it did work in the past and in other places that construct
does work, e.g.

   svnmucc -mm put <(echo foo) URL

Subversion has multiple ways to read a file and when reading from a pipe
(and that shell command constructs a pipe) the code that uses stat() to
get the filesize doesn't work because the pipe filesize is zero. There
is other code that doesn't use stat() and reads in block until EOF, and
that works for pipes. We might be able to fix the code that uses stat()
by having it check for EOF as well.
