Summary	0001252: Some files lose lens metadata in Panasonic RW2 from GH2
Description	A bunch of RW2 files processed just fine (repeatable). But then a particular set of files (repeatable) would lose the lens ID metadata in the Panasonic proprietary EXIF section so that DXO Optics Pro could no longer determine the lens correction module. Even the _orig file created had this problem. I changed the name of the xxx.rw2_orig to xxxorig.rw2 so that DXO would recognize it to test it and it could not determine the lens module again. This is very strange as the orig file should just be a copy of the original file. DXO works fine on the real original file.
Steps To Reproduce	Just run any date update, e..g to add 1 day to the dates of a batch of these files.
Additional Information	Default settings except update EXIF data to get the new date in there. Only writing "taken date." I can't upload a set of 3 good-behaving rw2 files and 3 bad-behaving rw2 files because of the upload limit. Each RW2 file is about 17MB.
Tags	No tags attached.
