The emacsclient session of Emacs appears to be initiated in a screen(1)
window (by the presense of the "STY" environment variable).

I think screen unconditionally sets TERMCAP, and this was what used to
bite me some times, which eventually led me to add to my .bashrc file:

  case $TERM in
      unset TERMCAP

Can you try running emacsclient outside of screen?  Does it behave in
the same way then too?
