If you want to convert all the white background, try the "by Color..." out of the
select menu and use the bucket fill afterwards.
If you want to select a particular white area which is surrounded by your curves use
the magic wand (is this the word in englisch?) ("Zauberstab"), the forth icon in the
toolbox and click in the white area. This tool selects an area until it reaches a
border with a "threshold"-difference to your starting point.
Think of it as a stone thrown into water, which produces waves. Those waves go on in
all directions, until they reach something, that stops them - in your picture this
border is a different color which differs threshold (Tool Options dialog) from the
starting color (where you clicked.)
Hope it helps
