bash 3.0-7 bug - prompt length with non-printing characters

I have a prompt ($PS1) which includes non-printing characters. They are
enclosed with \[ .... \] so that bash knows not to count them in discovering
the length of the prompt in order to position the cursor correctly.
On upgrading to bash 3, I noticed that the last few characters of my prompt
were erroneously duplicated (it ended with two $ signs). When tab completion
was used, the text got nastlily corrupted.
Here is a reproduction case:
PS1='\[\e[32;1m\]@\[\e[33;1m\]#\[\e[0m\] $ '
Curiously, appending '\[\]' to the end of $PS1 works around the problem.
Max.
