The shebang line is ignored if a file is sourced, isn't it?

 From a quick look at the code in environment-modules I see that it 
seems to test for the BASH_VERSION variable. That makes me think of this 
change of LightDM:

https://bazaar.launchpad.net/~lightdm-team/lightdm/trunk/revision/2168/debian/lightdm-session

which was made in response to:

https://launchpad.net/bugs/1482641

Can this possibly be a reason for the confusion you have observed?
