Incorrect Picture Pixbuf Displayed

[Cliff Carson]

Have a single photo library to hold all my pictures. Setup 2 Picture database directories using the --datadir paramter to hold different sets of pictures. Have had this setup for over a year and have not seen this problem. I'm currently running 12.10 (with a new level of Shotwell?) and am now seeing some pixbuf pictures from one picture DB show up when I start Shotwell to display the other DB. If I start up in DB 1 and select the bad pixbuf picture then enhance it the correct pixbuf picture shows up. I can then startup in DB 2 find the picture I corrected which should not be in DB 2. I can then enhance this picture to get the correct one but going back to DB 1 and find it incorrect again. This has nothing to do with the thumb files, have deleted all the files in the thumbs directories.

Appears that Shotwell maintains a single cache of thumnails in ~/.cache/shotwell/thumbs of the pictures in the database. The problem is that when using the --datadir (or -d) this same single cache is used for all databases resulting in the wrong thumbnail being displayed.

[Lucas Beeler (lucas-yorba)]

This issue is known upstream and is ticketed here: http://redmine.yorba.org/issues/5986

In the meantime, a workaround is this: whenever you switch your library, wipe out your ~/.cache/shotwell directory. This will cause Shotwell to generate new thumbnails appropriate for the current library.

As an alternative create a new ~/.cache/shotwell for each picture set (--datadir) using the steps appended by Lucas, rename the ~/.cache/shotwell as a unique directory names. When starting shotwell with the --datadir parameter link the appropriate renamed ~/.cache/[name] as ~/.cache/shotwell.
