gnome-terminal does not use login mode by default, which causes /etc/profile not to be sourced, and you get a non-gentoo-default prompt, shell does not act as it should since it's not in login mode. Suggest changing gnome-terminal's ebuild to patch the global config for it.
that's correct.. can you kindly provide a patch ? ;)
Created attachment 8598 [details, diff] Changes the default to a login shell. The patch applies cleanly, but that's as far as I've tested...
patch added to 2.2.1, thanks.
