How about reading the error messages?

Is that the version you are using?

A sequential music expression (which is what is in #{ ... #} in version
2.14.0) can't be a markup. Now in the current development version, #{
\markup ... #} will indeed work fine, but of course, it returns a
markup, and a music function still can't return a markup. Either way,
this does not fit.

I have no idea what you are expecting here.

Well, this is the \markup in an unexpected place. It tries skipping
it...

And tries looking for music again. It arrives at \fret-diagram-verbose
and since in music, escaped strings don't contain -, it stops after
\fret. Which it does not find convincing.

By the way: can you switch off the HTML mail you are generating in
addition to the normal mail? It is useless baggage.
