Special. With dpkg-query 1.16.1.2 on Precise:
$ dpkg-query -W -f'${Version}' zhpy
No packages found matching zhpy.
$ echo $?
1
$ dpkg-query -W zhpy
No packages found matching zhpy.
$ echo $?
1
$ apt-cache show zhpy
N: Can't select versions from package 'zhpy' as it is purely virtual
N: No packages found
As you said, I think we're still ok though in this specific case.
