I also have this problem. I am using Nikon NEF RAW files from D3100. Previous versions of shotwell would embed the exif data into the rendered JPG's - but the newest (0.11.6) does not for me. That is the Basic info is there and correct, but the Extended information is not. The Extended information is just showing the rendered jpg's name an location - eg - ~/Shotwell_Library/DSC_0991.NEF_<developer>.jpg
