this happens in linux mint to.
Hi Sergio, There are two problems here: the first is that OpenRaster (because it's based on PNG) doesn't support CMYK. Your image is CMYK, so Krita gets confused. I've added a check for that, and now Krita tells you about the problem. As for saving to PSD, I've tested that too, and while the saving succeeds, the result looks pretty mangled. I need to investigate that next.
