An error has occured

So one of my users got a very unhelpful error message when closing the calendar in their Notes client.

It says to see the error log for more details, but it would be helpful if it said where that error log was located. There is nothing in the normal log.nsf. I’ve seen other posts here and on Google that reference this having something to do with Eclipse. Does anyone have any thoughts?
