qbs crashes every time it is run

The qbs executable shipped with Creator crashes every time it is run. It has been the same in 4.12 beta 2, and it didn't change in the RC. This makes Creator 4.12 plainly unusable with qbs projects.

I was asked in the chatroom to build qbs myself and test like that. I'm sorry, I do not have the time to spend on that at this moment.

Here's what happens when running qbs on its own (which explains the error when run within Creator):

$ /Applications/Qt\ Creator\ RC.app/Contents/MacOS/qbs

fish: “/Applications/Qt\ Creator\ RC.a…” terminated by signal SIGSEGV (Address boundary error)
