Comment (by reeskm@…):

 I have attached a public domain DJVU file that crashes my install. It's
 the "Adventures of Sherlock Holmes. As soon as the title page is
 displayed, you get the standard Mac spinning wheel and then the app
 crashes.

 This should help reproduce the problem!

 I have some files that do not crash the app, but they are not public
 domain and so I don't feel comfortable posting them. You'll just have to
 take my word for now that they load and play fine.
