I have been using GNU Emacs running on Fedora Linux, with the emacs vm (View Mail) package, to read mail for a long time now. But as of a couple of days ago, a problem has developed.
Whenever I try to read a message that has inline HTML, I get the error msg Inline text/html by emacs-w3m display failed: (wrong-type-argument stringp nil) and the text of the msg is presented in HTML format.
This is a recent problem. The main thing that has changed is that we've upgraded from Fedora 28 to Fedora 29.
Any suggestions on how to fix this? Many thanks!
