Please describe the problem:
While using this bash prompt configuration gnome-terminal fails to display the
prompt correctly, there is a white rectangle before the "~" which should not be
there at all.

Here is what the prompt looks like with
Gnome-terminal:http://putfile.com/pic.php?pic=1/917483511.png&s=x12

Here is what it looks like with
Konsole:http://putfile.com/pic.php?pic=1/920091394.png&s=x12

Take note of the lack of the white rectangular line to the left of the "~"
(tild) symbol.

Here is the bash prompt code:

red="\[\033[0;31m\]"
green="\[\033[0;32m\]"
white="\[\033[1;37m\]"
PS1="$white\t \d \n\[\033\]$green\w>\[\033[0m\]"

Steps to reproduce:
1. Use bash prompt configuration
2. Open gnome-terminal  
3.
