Hello Brandon, can you try to open nautilus from a terminal, please? This might give us some extra error messages.
And please check if the command "net" from the package "samba-common- bin" is installed on you machine: Dec 6 21:15:28 BrandonsLaptop org.gnome.Nautilus[1601]: Nautilus-Share- Message: Called "net usershare info" but it failed: Failed to execute child process "net" (No such file or directory) This does not seem to be a dependency (and I found several PCs with working nautilus and without "samba-common-bin" installed). However installing this could help us to find the cause for your problem though. Best Regards Vej ** Changed in: nautilus (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1648215 Title: Nautilus fails to launch occasionally Status in nautilus package in Ubuntu: Incomplete Bug description: 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.
