I was sick of having to source the .bashrc manually in the terminal. Unfortunately it seems you can't automate this easily. To still get a nice shell I change the fingerterm.desktop to login locally via ssh.
# edit the "Exec" line from /usr/share/applications/fingerterm.desktop: [Desktop Entry] Type=Application Name=Local SSH Exec=sh -c "cd ~; unset POSIXLY_CORRECT; exec fingerterm" Icon=icon-l-terminal
