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.
