[Qgis-developer] Segmentation fault immediately after QGIS start

Hi,

With the newest master I get a segmentation fault immediately after 
starting. Even before loading a project.

Maybe this has to do with the recent start screen modifications?

Here are the last debug messages:

-----------------

Do you have any idea on what may be wrong? If no, I can go back in git 
history and try to find the commit that makes my QGIS crash on start.

Thanks,
