I discovered that Accordance could not amplify to several of my favorite workspaces. I could open them directly from the Finder, but attempting to amplify to them or to open them from the Library resulted in an error saying something about "only the file name X was expected" where X was the name of the workspace in question. If I dismissed the error alert and hit "cancel" in the open dialog, Accordance would crash most of the time. Sometimes it crashed just before I hit cancel.
I solved my immediate problem by removing the workspaces from the library, opening them, and re-saving them as favorite workspaces. But I thought I should report the crashes.
I did save the original workspaces in a zip file before fixing things, in case they would be helpful to identifying the problem. Let me know if you'd like me to attache them.
