Thanks to everyone for their interest in this topic.

In reference to
https://github.com/quicklisp/quicklisp-client/pull/128/, it is only a
minimal stop-gap measure which I found could fix the immediate problem
which I encountered. I know very little about ASDF and Quicklisp, so I
certainly had no conscious intent to assert that one condition or
another must prevail. Any improvements by more knowledgeable people
would be welcomed by me.

All the best,

A cheesy fix would simply be to wrap it in IGNORE-ERRORS. But it might cause errors in its present form.

This really is more a QL issue than an ASDF one (although it illustrates an issue with wrapping errors, IMO).
