That is most likely due to a circular dependency. The issue is that circular
dependencies are no longer handles properly by graph-depends since we use
show-info.

As you already found, the issue is because the package is not enabled (it is a
host package without a config.in option), and is also not in the dependency
chain of any other package.

The proposal I have is to add a check to graph-depends, that checks that the
requested root package is indeed enabled, and if not, inform the user rather
than spew a traceback.

Yes they are:
https://git.buildroot.org/buildroot/tree/support/scripts/graph-depends#n133 and
https://git.buildroot.org/buildroot/tree/support/scripts/graph-depends#n337

The code is there, but you don't get that far because 'make show-info' fails if
there is a circular dependency. For any package involved in the loop,
_FINAL_RECURSIVE_DEPENDENCIES will trigger a circular dependency error from
make. So show-info never prints anything.
