bug#64112: greetd-wlgreet-session doesn't source .bash_profile

[ytc]

Hello everyone.

I've noticed that when I started a Wayland session with a
greetd-terminal whose default-session-command is
greetd-wlgreet-sway-session or greetd-wlgreet-session, enviromental
variables set in .bash_profile doesn't seem to be set.

I don't know if this is a bug or feature but it doesn't seem right to
me.  I would be glad if you handle it.

Thanks in advance.
