That's actually a vte issue. Vte doesn't support anymore to set the TERM
environment variable. You can set the emulation, but it's not the same,
messing with emulation mode can lead to really bad results, so vte now
only supports XTERM emulation mode.

http://docs.xfce.org/apps/terminal/preferences (search for “Emulation”)
has some info about that, along with
https://bugzilla.xfce.org/show_bug.cgi?id=7178 and

For now, you can try to set TERM in your shell with something like:

# Enable 256 color capabilities for appropriate terminals

# Set this variable in your local shell config if you want remote
# xterms connecting to this system, to be sent 256 colors.
# This can be done in /etc/csh.cshrc, or in an earlier profile.d script.

# Terminals with any of the following set, support 256 colors (and are local)

if [ -n "$local256" ] || [ -n "$SEND_256_COLORS_TO_REMOTE" ]; then

  case "$TERM" in
    'xterm') TERM=xterm-256color;;
    'screen') TERM=screen-256color;;
    'Eterm') TERM=Eterm-256color;;
  export TERM

  if [ -n "$TERMCAP" ] && [ "$TERM" = "screen-256color" ]; then
    TERMCAP=$(echo "$TERMCAP" | sed -e 's/Co#8/Co#256/g')
    export TERMCAP

unset local256
