Cannot launch evince after upgrade to 9.10

This has happened three times while trying to open PDF files. The PDF doesn't open, and I get a red ! in the task bar. Following its instructions leads me here. I admit I'm a little confused; the previous two times I didn't follow the instructions as far as this because I didn't know what was going on!

Please let me know if I can do something more useful next time the problem occurs.
