I think your real issue here is that whatever this GUI launcher is,
it does nothing visible when told to launch an executable file that
is not a valid binary. It may have spewed some error into some log
file, but did not pop up a dialog saying "That isn't a valid binary"
or whatever. I don't think that you would get different results no
matter what setting you had for running terminals as login or not.
So if it bothers you that trying to execute garbage produces no
visible feedback, I think that is the bug you should file.
I don't think the login shell setting has anything to do with it. I
can't see why whether it is a login shell or not has any bearing on
what happens when the system tries to execute a file of junk.
