15 bushwalkers in a Macpac Minaret? I think I have found the cause of said "overcome by fumes" and it had nothing to do with fuel, well, stove fuel...
On topic, I use shellite stoves, and I have cooked in the vestibule without problem, but WITH
GREAT care.
I have also cooked in the tent once, though it was in the Hallmark Snowcave with front and back doors fully open, that is, just the mesh, so there was still good ventilation.
Read about why,
HERE.
Here's a pic of the stove we used on said indoor cooking event -

A couple of photos of cooking in a vestibule...
Firstly, using the camera tripod to hold the outer tent well back from the heat. Also note the opening at the top to help t he gases escape. MSR Simmerlite in action here.

And another way to allow gases to remain out of the main inner tent, is to peel back the inner (if your tent allows that) to make the vestibule space much larger...
This one's the Optimus again. A fantastic little stove, though a bit heavy.
