Usually, a "black" image means that the original image either doesn't exist or the transparency was done incorrectly. Odd that its works on the ROM you pulled it from though. Is there any way that you could send me your status_bar_background? I will see if I can edit it and put it in a .zip for you. If that doesn't work, I'll download the ROM that you're on and edit the image. Then you should be able to just flash the ROM without wiping..that may work.
