SOLVED: bash upgrade, prompt issues

Question

Just did a pacman -Syu and it fetched bash-4.0.033-1. However now whenever a open a bash shell as a user (not root), my prompt has this at the start:
0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~} (~)
... followed by the usual [user@host ~]$
Now I assume this is caused by this line in profile.bash:
PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME%%.*}:${PWD/$HOME/~}\007"'
export PROMPT_COMMAND
Unfortunately there is no backup of said file, so I have no idea what this line used to look like. I'm going to hazard a guess that "\033]0;" should be a "[", and "\007" should be "]".
Edit: Forgot to mention that I'm using rxvt-unicode for the terminal.
Edit2: It seems the relevant file was /etc/bash.bashrc, and the solution was to simply remove rxvt-unicode from the if statement.

Answer 1

Okay, there's something else going on here. I just happened to be messing with ANSI escape codes for something else and the same issue arose.
For instance
[ptepid@securis ~]$ echo -e "Test1 \033[1;34m Test2 \033[0m"
1;34m Test2 (~)Test1 Test2
[ptepid@securis ~]$
That echo statement should print "Test1 Test2" with test2 in blue (not shown here). It does that, but it's also spitting out the escape codes as garbage beforehand.
Turns out only one user is affected. I'm trying to hunt down what is causing it, but I can't find any ENV variables that are different. It's only happening in X, but it's a problem with both rxvt and rxvt-unicode.
SOLVED: Okay, now I feel pretty dumb. It was some bogus code in my .bashrc that was meant to update the titlebar of an xterm. That worked, but it also seems to mess with ANSI escape characters. This was the offending code:
if [[ -n "$DISPLAY" ]]; then
if [[ -n $MRXVT_TABTITLE ]]; then
trap 'echo -ne "\e]61;${BASH_COMMAND//\"/} (${PWD/$HOME/~})\a"' DEBUG
else
trap 'echo -ne "\e]0;${BASH_COMMAND//\"/} (${PWD/$HOME/~})\a"' DEBUG
fi
fi
A relic from when I'd used mrxvt.
