I just noticed that I can no longer create new projects. I had the previous nigthly build installed (on debian) and updated now to this one, but that didn't fix it.
I simply get no choice of project wizards, so the OK button is disabled and I can't create anything. With right-click I get offered to modify the config.script, but well, I don't really have an idea what would be wrong in there. I post it in case anyone sees something and can help me:
