"The shebang line is ignored if a file is sourced, isn't it?"
You tell me! I'm sure your guess is better than mine. All I really know is that
at some point in the initialization process dash comes into play and is not
equal to the task. I know this because the initialization works as expected if
I change /bin/sh to point to /bin/bash.

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?
