I've had similar experience in DT 2.0.7 or earlier on ubuntu. What happen however was that after the crash and re opening - the light table thumbnails were wrong (not accounting for the edits). When I did open the image in dark table all the edits were there. So just going back and forth between DT mode and LT mode would fix the thumbnails.

Not sure how DT 2.2 would behave. You may want to back up the xmp files and try simply opening the files in darktable (editing) my expectation is that the edits would be there.

Also - DT 2.2.1 is the latest stable release as far as I know.

@ Patrick, thank you! I will give that a try.

About half of the photos are raw files, the rest are jpgs. Does the fix you mention only work on raw files?

The images are from a Fuji X-T10, and for many of my darker indoor shots (behind-the-scenes concert photography, in this case), it's easier to get what I want by working with the associated jpgs. Otherwise I find myself having to fiddle with the base curve a lot more than I can afford to, time-wise.

Fuji must use a lot of complex AI in its in-camera jpg processing, because I can't seem to come up with a single good basecurve to serve as a starting point. The one included with dt is always wrong in the darker areas, and requires very touchy minute adjustments (even touchy in the logarithmic view) that are really hard to control. When shooting Canon, I used to only play with the raw files, as the profiles for it in dt gave me a really good starting point. It's much harder with Fuji's x-trans files, hence my working with jpgs.

    darktable saves it's edits to the accompanying xmp files. you can
    probably recover the unsaved work by going to "darktable
    preferences" ->
    "core options" and selecting "look for updated xmp files on startup".

    i am assuming you *are* working with raw files.
