That's indeed an intersting question. Maybe files of these dimensions
simply exceed the specifications (or expectations) of a WAV file.

I don't know the mediainfo tool (it does not seem to be available from
the Debian archive), but I guess that the aforementioned packages all
pretty much share their WAV-decoding code. What does the file(1)
utility say (what does ffmpeg say) and what happens if you put the WAV
file back into a container, say MKV or OGG?

Alright, that's a completely different issue (and certainly worth its
own bug report) and I'll try to have a look at it sooner or later.
