I think that this problem should be fixed at OS level, for example by using encrypted /home filesystem. > > Geeqie now uses text files for storing keywords and comments.

The problem is that the functionality for working with XMP sidecars was added to Exiv2 0.17 which was released 3 months ago. The older versions are comparable to the internal implementation - no XMP support. That means that without recent Exiv2 there are just two options - use the old text files or do not write comments and keywords at all. I don't think that we can hard require Exiv2 0.17 at this time.
