Opus crash

Installed the newest version yesterday, with no issues. This morning I had logged in with the machine just sitting idle for a couple of hours, and just the startup process of Opus started. When I opened my default lister for the first time, Opus crashed. Event log says:

Is it reproducible?

So far, no, so it could have been just a fluke.
I'll post back if it happens again.
