Hi Christian,
I confirm I get it working with Qt-creator and qbs from master.
But I also experienced repeated crashes when opening some qbs files in
qtcreator...
So maybe I will way this get's released before using in production.
Is it planned to have qbs 1.4 in next Qt 5.4 release ?
Thanks for your help solving this.
Stéphane
