Linking application with static Qt version built with -qtnamespace fails when using QtLocation or QtPositioning in qml

Static linking with QtLocation and QtPositioning worked fine using Qbs 1.12.x, but using Qbs 1.13.0, the linking of the attached example application reports

...../qbs-location.05c772c0/qml_plugin_import.cpp:4: error: undefined reference to 'qt_static_plugin_QtLocationDeclarativeModule()'
...../qbs-location.05c772c0/qml_plugin_import.cpp:5: error: undefined reference to 'qt_static_plugin_QtPositioningDeclarativeModule()'

It works fine as expected using dynamic linking.

To reproduce, build Qt 1.12.3 (or similar) statically and configure with a namespace (./configure -static -qtnamespace <somens>) and use as Qt version for the build.
