OK, I think you missed part of my previous post:

I filed it. But IMHO digiKam core doesn't perform as expected either. When I
tried to convert png->jpeg by "save as..." in image editor, I got:
Cannot save metadata using Exiv2  (Size of IPTC JPEG segment is larger than
65535 bytes)
on the console, what means that it in fact recognized the problem, but the
result is that the resulting image is stripped from BOTH iptc and exif
metadata. I think a better way of handling this would be to strip just the
iptc section (exactly what I did with IM's convert). Is this a bug then?
