I'm not saying that setup.ini isn't triggering the bug in 'setup.exe' but I 
still contend if 'setup.exe' can't function properly in unattended mode due
to an external change then this is a bug within 'setup.exe', no
matter how long it has been since its last release.  Of course, a motivated
individual looking for a workaround could certainly remove the newest
packages from their local 'setup.ini' file to see if that helps.  If so,
one could then narrow in on the package that's causing unattended mode to
