This code handles the saving and displaying in question (quick look hop i
am right :)

   2282 (defun notmuch-show-save-part ()
   2283   "Save the MIME part containing point to a file."
   2284   (interactive)
   2285   (notmuch-show-apply-to-current-part-handle #'mm-save-part))
   2286 
   2287 (defun notmuch-show-view-part ()
   2288   "View the MIME part containing point in an external viewer."
   2289   (interactive)
   2290   ;; Set mm-inlined-types to nil to force an external viewer
   2291   (let ((mm-inlined-types nil))
   2292     (notmuch-show-apply-to-current-part-handle #'mm-display-part)))

SO, there is 2 options:

1) mm executes save part correctly but not display part

2) there is (shell) wrapper program executing zathura which cannot handle
   arguments with spaces (there is plenty of examples of this!)


You could try to check how th external processes are executed by executing:

strace -f -e trace=process emacs -f notmuch

(emacs on X is preferable in this case ;)
