Thanks for that hint. This gives indeed more details but actually 
confirms the prior finding:

Debian's fc-list finds (shortened output, and deliberatly choosing the 
Bold Italic case):

Font 98 Pattern has 24 elts (size 24)
        family: "TeX Gyre Adventor"(w)
        style: "Bold Italic"(w)
        fullname: "TeXGyreAdventor-BoldItalic"(w)
        file: 
"/usr/share/texmf/fonts/opentype/public/tex-gyre/texgyreadventor-bolditalic.otf"(w)
        fontformat: "CFF"(w)
        postscriptname: "TeXGyreAdventor-BoldItalic"(w)

LilyPond's fc-list finds

Font 255 Pattern has 19 elts (size 19)
        family: "TeXGyreAdventor"(w)
        style: "BoldItalic"(w)
        file: "/usr/share/fonts/X11/Type1/qagbi.pfb"(w)
        fontformat: "Type 1"(w)
        postscriptname: "TeXGyreAdventor-BoldItalic"(w)

After the section with the detailed font patterns there is a list with 
concise entries.

There Debian's fc-list finds

/usr/share/texmf/fonts/opentype/public/tex-gyre/texgyreadventor-bolditalic.otf: 
TeX Gyre Adventor:style=Bold Italic

while LilyPond's finds

/usr/share/fonts/X11/Type1/qagbi.pfb: TeXGyreAdventor:style=BoldItalic

So I realize that my problems in Frescobaldi stem from the fact that 
LilyPond finds different fonts than the operating system. But I don't 
really have an idea as to what to make of it.

Currently it looks like my best bet would be to simply split a reported 
style of "BoldItalic" in two words but leave it as it is in other cases 
(e.g. leave SemiBold alone). This really doesn't feel like a sane 
solution ...
