Chromatic Abberation errors, blue halo

Hi!

I am using the default demosaicing functions in libraw (AHD), and i have the automatic chromatic abberation correction on. Often this works really well. Just sometimes however, this gives very strange results as can be seen in the attachment. I call it purple or blue halo's. I am absolutely sure it has to do with the chromatic abberation detection. Any ideas or questions?
