I feel like my reviewers often can't reproduce my errors. I'm running Emacs from a very recent commit and I have mutool installed. I really feel like the error should be reproducible for anyone that meets those two requirements. Do I need to include more information in my bug reports? If so, what information? Anyways I modified my patch with Tassilo's feedback. However, I realized that it partially reverts commit b23e062d7463b76d25dfd9ba4a80c1848a448e42
