Comment 5 for bug 701737

So, this doesn't happen on any .ARW file, just a particular one?

One way you can find the file is to do this:

Run Shotwell from the console like this:

$ SHOTWELL_LOG=1 shotwell

Import all the photos you did before. When it crashes, upload the following file to this ticket:

~/.cache/shotwell/shotwell.log

If you open this file, you should see all the file names as they're imported. It's probably the last one or the second-to-last one that caused the problem.
