TypeError when static library depends on static library

The attached test project has the following structure:

Project

• App [CPP Application] (depends on Shared / Base)
• Shared [CPP StaticLibrary] (depends on Base)
• Base [CPP StaticLibrary]

Building the project results in the following error:

/usr/share/qbs/modules/cpp/GenericGCC.qbs:382: error: TypeError: Result of expression 'inputs["obj"]' [undefined] is not an object.

When removing the line:

{{Depends { name: "Base" }}}

from the Shared.qbs file outside the Export section, the project builds. Syntax highlighting within Shared, however, is then broken.
