For all F-Spot lovers: Here is a plugin which merges versions of photos to their originals e.g. after a database import: click to download
This plugin searches through the existing F-Spot database for orphaned versions of photos, i.e. photos that should be versions of other photos but are separate photos.
appear as two separate pictures, but the „Modified“ one should actually be a version of the first one.
The MergeVersions plugin searches for pictures named „[name] (Modified).jpg“, „[name] (Modified (2)).jpg“ and so on (up to #4) and merges them as versions into a photo called „[name].jpg“ if it exists.
How I got to it
After all the exif time data got screwed up somehow (no idea why), I restored a backup of the photos. But then the times were not correct in F-Spot. As I wanted to clean up my photo directory anyway at some point in time, I went through the painful process of re-importing all photos. Then, of course, the modified versions were not correctly imported. Thus, writing a plugin that kind of does this thing for me.
