nautilus doesn't start under heavy load

Question

When my system running Ubuntu 14.04 is under a heavy load (for instance a long video encode) nautilus fails to start. I've seen this similar question: Nautilus occasionally stops working

But although the error when launched in terminal is identical, Could not register the application: Timeout was reached it doesn't appear to apply in this case.

I tried all the answers in the aforementioned similar question.

Results are as follows

me@zippy-64bit:~$ killall nautilus
me@zippy-64bit:~$ nautilus -q
Could not register the application: Timeout was reached

me@zippy-64bit:~$ killall nautilus
me@zippy-64bit:~$ nautilus
Could not register the application: Timeout was reached

I ran a nautilus self-check with the following results:

me@zippy-64bit:~$ nautilus -c
running nautilus_self_check_file_utilities
running nautilus_self_check_file_operations
running nautilus_self_check_directory
running nautilus_self_check_file
running nautilus_self_check_canvas_container
running nautilus_self_check_file_utilities
running nautilus_self_check_file_operations
running nautilus_self_check_directory
running nautilus_self_check_file
running nautilus_self_check_canvas_container

gvfs-mount shows no remote mounts as seen below.

me@zippy-64bit:~$ gvfs-mount -l

me@zippy-64bit:~$ man nautilus
me@zippy-64bit:~$ nautilus
Could not register the application: Timeout was reached

gksu nautilus launches instantly perhaps due to a super user task being launched at higher priority.

I'd like to determine if extending the timeout under these conditions would allow nautilus to open. Is there a way I can accomplish this or any other effective workaround? Ideally I'd like to accomplish this without interrupting the encoding job currently running.

@Pilot6 There's a thought. I've become fairly accustomed to some of the features in nautilus that assist my workflow such as open, open with, bookmarks and such. It doesn't seem that mc has these features. Am I missing something? Is there a closer relative with similar features? — Elder Geek, May 01 '17 at 12:44

This problem was resolved by installing nemo as suggested by @Fabby in a comment here.

I installed with:

sudo apt-get install nemo
