Red and Blue swapped on jpeg import

[Skaven252]

I've occasionally created some tone-mapped pictures from multiple exposure brackets using the Luminance HDR program. But when I import the jpegs exported from Luminance to Xara, their Red and Blue channels appear to get swapped.

I can fix it by using a Live Effect. But why does this happen? Is there a way to losslessly avoid this before importing to Xara? Because Live Effects impose their own resolution limitations on the image.

Thanks!
