Description Milan Knížek 2012-10-08 14:55:42 UTC 
When adding caption (description) to images in other languages than x-default, then these captions are not saved to image (JPEG). However, once a caption for the x-default language is added, _all_ the existing language variants of the caption are saved to the file.

Reproducible: Always

Steps to Reproduce:
1. Use a new message w/o any metadata. Make user saving of metadata to images is allowed.
2. Choose af-ZA language for Caption. Type in some caption. Click apply.
3. Switch to CLI and run `exiv2 -pa image.jpg  | grep -E "Xmp.dc.description|Xmp.digiKam.CaptionsAuthorNames|Xmp.digiKam.CaptionsDateTimeStamps"`
4. Note that only (!) data in the latter two keys will exist.
5. In digiKam, add some caption to "x-default" language and Apply.
6. Switch to CLI and run the exiv2 command again.
7. This time, Xmp.dc.description has some values for both af-ZA and x-default languages.
Actual Results:  
Without some text in x-default language of Caption (Description), no description is saved to image.

Expected Results:  
Description should be saved to image no matter which languages are used.

Setting the Exif comment (which is using only the x-default comment, and is removed if only a specific language is added) failed although it should not

Do not forget to return true, and thus fail, when removing the exif comment.
