I think I figured out what caused it. I started Fuse… it notified me an update was available. I installed the update and started Fuse. But I think the daemon was still running.

Perhaps add a process that shuts down any active fuse installs during install of a new one?

Thanks for reporting! Shutting down Fuse from the installer is definitely on our list of things to do. We already do it on Windows, and should do it on OS X too.
