Nautilus will not run

[Robynsveil]

I've had a search this evening to see if anyone else has encountered this issue: I can't find any similar instance.

I'm not fond of Unity, so I'm running Gnome Classic in Ubuntu 12.04 LTS. I've recently been getting these internal error notifications, but nothing seemed to be amiss so I only ever looked at the most recent one. It appeared to be about the applets that were causing problems.

I only mention this because I'm not sure it is a related problem. I clicked on the Home Folder icon (next to Applications | Places at the top) but nothing happened. I then tried to run nautilus from the cli and got:

me@my-laptop:~$ nautilus
Could not register the application: Timeout was reached

On another thread, someone recommended using something called gdb... which I ran, and got:

me@my-laptop:~$ gdb nautilus

Any idea what the problem might be and how to fix this? Thanks in advance to any and all who respond.

Try to restart Nautilus with the following command and see if it starts from the icon. Post any errors generated by using the command .

nautilus -q

Thank you for your answer, Frog's Hair. I actually found that if I disconnected my external terrabyte drive, Nautilus came back all of its own. Apparently, there's an issue with my terrabyte drive which caused Nautilus to time out.
Thanks again for replying... I'll try to reconnect the drive and see if the problem reproduces itself... and try your command.
