Project will not open

Since upgrading to Yosemite I have not been able to open one particular project. (Others open without any problem.) Scrivener immediately crashes after opening this project. I’ve poked around in the .scriv package contents and my work appears to be preserved. Duplicating the project triggers a dialogue box when I open the project that gives me the option to copy the project (within Scrivener), but when I tried to do that Scrivener crashed immediately.

Any ideas?

What I’ve done is to create a new project and import the old one into it. Not ideal, but at least I’m up and running.
