Description justjunk 2015-02-03 23:56:35 UTC

Moving from Win Vista to openSuse 13.2, all pictures initially tagged by Windows Photo Gallery were imported to digiKam. This worked like a charm, except that in rare cases the Windows-originating tags are not recognised. That is, digiKam reads them and displays them in the right-handside EXIF metadata information (Image Information / Windows Keywords), but does not recognise them as digiKam tags, as can be seen in the mouse-over "digiKam Properties" display. Please see attached screenshot files snapshot1.tif and snapshot3.tif: "Tags" is empty. To facilitate reproduction, the picture files are also attached.

Reproducible: Always

Steps to Reproduce:
1. Import attached 032a.jpg and/or 075mod_v1.JPG files.
2. Compare metadata as displayed in Metadata/EXIF, "Image Information", "Windows Keywords" with "Tags" in "digiKam Properies", as the mouse cursor rests on the picture in eg. Thumbnails view.

If no XMP or IPTC keywords exists, according to EXIF Windows keywords are searched.

exifkeywords2.patch

The new function returned a "true", even though the image tag "Exif.Image.XPKeywords" did not exist.
