The Eraser tool creates transparency only if the layer has an alpha 
channel (Layer>Transparency>Add alpha channel). Otherwise erasing is 
like painting with the background color. Note that if you save to JPEG 
or other image formats without support for transparency, transparency is 
replaced by the background color as well.
