This is caused by +changes in mm-display-external in mm-decode.el. + +Ideally, we would put this output in the notmuch errors buffer but the +handler is called asynchronously so we don't know when the output will +appear. Thus if we put it straight into the errors buffer it could get +interleaved with other errors, otoh we can't easily tell when we +have got all the error output so can't wait until the process is complete. + +This patch just takes the simplest approach and discards the error +output (which means the behaviour is the same as it was with emacs pre +24.3). +--- +As I say above it would be nice to capture the error output but it +does not appear to be simple. This is probably worth applying in the +meantime as we definitely don't want the stderr/stdout appearing in +the show buffer. + +The bug is easy to reproduce: make a script which outputs to stderr or +stdout and call it on any part with ". o scriptname" (in fact even +". o ls" will do!) + +Best wishes + +Mark + + + + + + + emacs/notmuch-show.el | 9 ++++++--- + 1 files changed, 6 insertions(+), 3 deletions(-) + +diff --git a/emacs/notmuch-show.el b/emacs/notmuch-show.el +index 904b98e..42438ba 100644 +--- a/emacs/notmuch-show.el ++++ b/emacs/notmuch-show.el +@@ -2044,9 +2044,12 @@ caller is responsible for killing this buffer as appropriate." + This ensures that the temporary buffer created for the mm-handle + is destroyed when FN returns." + (let ((handle (notmuch-show-current-part-handle))) +- (unwind-protect +- (funcall fn handle) +- (kill-buffer (mm-handle-buffer handle))))) ++ ;; emacs 24.3+ puts stdout/stderr into the calling buffer so we ++ ;; call it from a temp-buffer. ++ (with-temp-buffer ++ (unwind-protect ++ (funcall fn handle) ++ (kill-buffer (mm-handle-buffer handle)))))) + + (defun notmuch-show-part-button-default (&optional button) + (interactive) +-- +1.7.9.1 +
