"Write IPTC Metadata to Master" no longer functioning for JPGs in Lion
I'm currently running Aperture 3.1.3 and I just upgraded to Mac OS X 10.7 Lion (with Filevault 2 enabled) yesterday and I've now got a problem that never existed before.
I've noticed that the "Write IPTC Metadata to Master" function no longer works when trying to embed IPTC metadata into any master file other than a RAW photo file. I thought maybe reparing permissions, repairing the Aperture library, rebuilding the Aperture library, reprocessing masters, regenerating previews might help ...nope.
To test this I created a brand-new Aperture library and imported a mix of .JPG and Canon .CR2 photo files.
I am able to successfully use the "Write IPTC Metadata to Master" command on my CR2s, but when I try to do the same thing to my JPGs I get the following error: "No master files were modified -- Aperture was not able to modify one or more master files because they have a format that does not permit modification."
JPG file IPTC metadata embedding worked perfectly in the past, but not now...
Anyone else notice this? Help/suggestions/advice?
