Hi, I hope I'm writing at the correct place. I'm running Emacs 24.3.1 on an Arch. I can M-x shell and run octave, or even octave -i --no-line-editing just fine. However M-x run-octave hangs indefinitely. After M-x toggle-debug-on-quit and C-g during the hang I get this backtrace: Debugger entered--Lisp error: (quit) accept-process-output(#) inferior-octave-send-list-and-digest(("more off;\n" "PS1 (\"\\\\s> \");\n" "source (\"~/.emacs-octave\");\n")) inferior-octave-startup() run-octave(nil) ... (rest deleted) My .emacs-octave is empty, I didn't have it, but even before creating it I had the same error, only the last value of the list to digest was nil. I get an inferior octave buffer created which greets me with the standard stuff but I'm missing a prompt. Writing in it is possible but provides no feedback.
