When opening files in Mac OS X, you get in addition to the normal file system browser a media browser that shows Movies, Music, and Photos. The Photos entry (at least on my system) consists solely of the iPhoto library, you can see the albums and smart albums there (things like Last Import).
However, this can get out-of-sync with the real iPhoto library. Right now, Last Import does not show the last import, but a previous one (not sure if it is the previous one). Even after a few minutes, it does not catch up.
How does this work, how could it have broken, and how can I fix it?
It might be related to my iPhoto crashing all the time, but even after a regular shutdown I still cannot see my Last Import in the Open File dialog.
