Uh, this was unexpected.  I believe it's because label-less inputs are
auto-generated via the package *name* rather than their variable name...
Since qtwebengine-5 (the variable) still has the name "qtwebengine", the
following code:

--8<---------------cut here---------------start------------->8---
(qt-process-path (string-append (assoc-ref inputs "qtwebengine-5")
                                      "/lib/qt5/libexec/QtWebEngineProcess"))
--8<---------------cut here---------------end--------------->8---

Doesn't actually find "qtwebengine-5" and it fails attempting to append
#f to "/lib/qt5/libexec/QtWebEngineProcess.  The solution that comes to
mind would be using:

(file-input-search inputs "lib/qt5/libexec/QtWebEngineProcess").

Thanks,

Maxim
