Must build twice to have Qbs run Qt's rcc on resource files

I have a large Qbs project with several libraries and applications. Some libraries and applications use the Qt resource files to bundle qml files etc.

If I have a "large" set of changes before building, Qbs will sometimes not run rcc. When I then build again, rcc will be run, the resulting files will be compiled and the applications are linked again.

This often happens if I get lots of changes from git - it's not that obvious when working on just a few files at a time. Seems like it's triggered when we have changes in both .cpp/.h files as well as the files only listed inside the .qrc files.

Currently our workaround is to always build twice to be sure.

Please let me know where to start looking to figure out this one (enable logging, ...?)
