Makes sense, I guess. It would probably make less sense when opening a not-yet-
opened document directly in a new window, esp. not if that ever becomes an 
optional default behaviour. In that case it would conflict with the possibility 
to keep the main window for the navigator and (maximised) output panels.

So setting the font via the .ui file (using the Designer or otherwise) never has 
the effect one might expect?

Why yes, that's fairly obvious. What's much less obvious is why it would quit 
almost as soon as I start it, before I even see a window.
I'd use a debugger to break on the location where the QProcess error is printed, 
but the issue has been unpredictable until now, and it would require me to 
rebuild at least QtBase with LTO (which apparently produces shared libraries 
without debug information on OS X).
