I accumulated years of edits over my photographs in Picasa. Picasa works as a non-destructive editor, so it doesn't change the original files but saves all modifications in its database and in picasa.ini files (a plain text file) in the same folder where the originals are stored. It then (reads and) applies those modifications on the fly when you see your photos within Picasa (but you don't see them if you navigate your collection with another viewer, of course).
I changed from Windows to Ubuntu OS in 2011, but kept on using Picasa (for Linux) in lack of a better alternative. Google discontinued support for Picasa for Linux a time ago, so I am more urged to find a free picture manager and non-destructive editor within Linux. I am considering something within the Shotwell--Darktable range (they are both non-destructive editors).
However, I would like to import my photo collection with the edits I made in Picasa so the new editor can apply them on the fly over the original versions (instead of exporting the modified photographs and import them modified, or duplicating storage by keeping both the original and modified versions). And then I can get rid of Picasa.
Do you know of any Linux non-destructive photo manager/editor that can import picasa.ini edits (transforming them into their own database o sidecar file format)?

[Edit 2 (2017): Not useful to translate edits, but may help someone reading: see this answer about a plugin to import some work done in Picasa (such as Albums, captions, tags and stars) into Lightroom. This other answer explains some other alternatives]
