Unfortunately, there's still a problem when Exiv2 is supposed to load the metadata corrupted by convert program. The image->readMetadata() call in kexiv2.cpp:381 says:

Warning: IPTC dataset Iptc.Application2.Preview has invalid size 120301; skipped.
Warning: Failed to decode IPTC metadata.

It's happening during construction of the metaTgt object in convertimagesdialog.cpp. So the object is broken and further call to metaTgt.applyChanges() throws Exiv2 error 22: Input data does not contain a valid image.

The first solution that comes to my mind is to use source metadata as a base for removing the preview, but then we loose the changes to metadata that convert program probably does.
