Change the second mapping to:

nmap <silent> <leader>te :!/usr/bin/xfce4-terminal &<CR>

The ampersand tells your shell to run the command in the background.

Instead of using :!sed -ri {sed program here} %
Try: :%!sed -r {sed program here}

In the first case, Vim launches a shell and runs `sed` with the current
file as an argument. Vim has no way to know that you've intentionally
run it with the '-i' in-place replacement, so it runs its usual "The
file changed from under me" logic. In the latter case, Vim is filtering
the selected lines through the `sed` program ('%' is equivalent to a
range of 1,$ [i.e. the entire file]).
