I guess that means that the audio codec used for the dv file can't be
used in a .wav container. I thought DV always used LPCM, but perhaps
that's my mistake.
You can just drop the -c:a copy; that will convert it to linear PCM
(probably at smaller bitdepth, but that's fine, will have to be
downsampled anyway).
If that also fails, maybe run this:
ffmpeg -i -t 60 -c copy fragment.dv
which creates a one-minute sample in "fragment.dv", and then put that
oneline somewhere, so I can see what's happening.
