Latest version seems fundamentally broken Rated 1 out of 5 stars

It's always been a bit temperamental in the past, but the latest version simply seems to throw [Exception... "[xpconnect wrapped nsIURI]" nsresult: "0x804b000a (NS_ERROR_MALFORMED_URI)"errors now when trying to connect to Google Calendar via Lightning. It also seems to hang on startup, to the point where I had to start Thunderbird with the "-p" option and delete my working profile entirely to start afresh. Shame...
