Doing some experiments running the tests manually, it appears the 
culprit is the "--all-targets" option
passed to cargo test by the autopkgtests. This seems to stop cargo from 
building the examples in a
runnable form.

I'm not sure what the best way forward here is, one could override 
debian/tests/control, but experiance
shows that is a maintinance burden, because debian/tests/control 
hardcodes the crate version.

The other option would be to just disable the tests in question. Not 
ideal but probablly not a disaster
either.

Does anyone have any better ideas?
