I think we will need to put out a 1.1.1 release to address this since  
packaging has already started and in some cases the packages are in  
use via repos etc already. I am happy to do the 1.1.1 release as an  
immediate follow on from the 1.1.0 release.

Juergen is it possible to backport this fix to stable branch too if it  
is not an invasive change? It sounds like maybe the project file  
format is getting changed so maybe it is quite invasive?
