As that seems only necessary when using gtk-webkt2 on html-only messages, I tried recompiling with gtkthtml.   As that didn't work, I vaguely recall the discussion deciding to drop it.

Yes, gtkhtml is deprecated & probably full of security issues…

Oooops…

Also, I'd like to confirm that html2text is only called on html-only messages.  Related question - why is html2text called at all when fetching messages (POP3) from the server.

Good question.  It is used in html.c, function html2text(), which in turn is called from libbalsa_html_to_string(), which in turn is /only/ called from mime.c, process_mime_part().

html2text is rather old and the “last resort” option.  Could you try to install python3's html2 markdown (on Debian package python3-html2text), and try if this works better?  And you could try to just kill the apparently hanging html2text process and see if Balsa stops hanging.

Cheers,
Albrecht.
