Public bug reported: Every once in a while, Nautilus will fail to launch. Clicking it's icon in the Unity launcher will either open up a black window, outlined only by its shadow, or it just flashes in the launcher and nothing happens.
Sometimes when this happens, it can be fixed by killing Nautilus entirely and re-opening it again. This time when it happened, it looks like it had something to do with media information with unity-music- daemon, however this machine doesn't have anything setup in either Banshee or Rythmbox yet. Here's a video capture of it happening: https://www.youtube.com/watch?v=gJdzED7z9nQ The system log seen in the video, from when it crashed, to when I relaunched Nautilus after killing it, is pasted below. I asked on the Ubuntu forums about this and a few others said they are having the same issue, but since I found no bug related to this directly on launchpad, I decided to open one myself.
