You have been subscribed to a public bug:

When VNC'ing into gnome-session-flashback (Metacity) with either
tightvncserver or vnc4server configured for non-shared desktop mode,
when one opens a terminal for example, and types the "s" key, it acts as
if the Super key is also pressed along with it. Hence, this appears to
be a gnome-* issue.

Vivid new install setup for tightvncserver:
sudo apt-get update && sudo apt-get -y dist-upgrade && sudo apt-get -y install xrdp gnome-session-flashback && sudo apt-get -y remove vino && nano .xsession
#START
export XDG_CURRENT_DESKTOP='GNOME-Flashback:Unity'
exec gnome-session --session=gnome-flashback-metacity --disable-acceleration-check
#END

sudo nano /etc/xrdp/xrdp.ini

change to:
#START
[globals]
bitmap_cache=yes
bitmap_compression=yes
port=3389
crypt_level=high
channel_code=1
max_bpp=24
#black=000000
#grey=d6d3ce
#dark_grey=808080
#blue=08246b
#dark_blue=08246b
#white=ffffff
#red=ff0000
#green=00ff00
#background=626c72

[xrdp1]
name=sesman-Xvnc
lib=libvnc.so
username=ask
password=ask
ip=127.0.0.1
port=-1
#END

Log out, log back in, and RDP in via either Windows Remote Desktop
Connection or Remmina.

WORKAROUND: Applications > System Tools > System Settings > Keyboard >
Shortcuts > Disable all shortcuts containing the Super key.

WORKAROUND: Don't use the .xsession file with tightvncserver, but this
then creates a shared desktop experience, instead of ones own, not seen
by the user at the local console.
