Having (some) files unsupported by the plugin but with UTIS included in "public.audiovisual-content" makes quicklook previews/file moves etc hang indefinitely

Maybe related to https://github.com/Marginal/QLVideo/issues/112 I noticed that having (as an example) .mid or .sf2 (soundfont files) in my Downloads folder (which I also have as a stack in the Dock) makes quicklook previews hang indefinitely (not sure if only for the current folder, as an example my Dock ~/Downloads stack eventually turns into a bunch of empty boxes) and the affected files can't be moved/renamed etc. As it turns out, both of those are included in "public.audiovisual-content":

.mid:

kMDItemContentType                 = "public.midi-audio"
kMDItemContentTypeTree             = (
    "public.midi-audio",
    "public.audio",
    "public.audiovisual-content",
    "public.data",
    "public.item",
    "public.content"
)

.sf2:

kMDItemContentType                 = "com.soundblaster.soundfont"
kMDItemContentTypeTree             = (
    "com.soundblaster.soundfont",
    "public.audio",
    "public.audiovisual-content",
    "public.data",
    "public.item",
    "public.content"
)

As far as I can tell, removing the affected files/extensions is the only way to prevent this from happening with the quicklook extension active.

Issue also applies to (much more common) .ogg files

Should be fixed in the latest release.
