iMac is shutting down when it attempts to sleep with 'hibernate image' error

More information:

1. It looks like the crash/shut down is happening when the display tries to sleep (timing is 15 min after the beginning of automatic sleep).

2. When sleep is first initiated, I am seeing this in the console (not normal?):

The iLMBPhotosPlugin file does exist:

ls -al "/Library/Application Support/iLifeMediaBrowser/Plug-Ins/iLMBPhotosPlugin.ilmbplugin/Contents/MacOS/"

total 80

drwxr-xr-x 7 root wheel 238 30 Jan 07:46 ..

-rwxr-xr-x 1 root wheel 99840 29 Sep 01:41 iLMBPhotosPlugin

The Library PhotoLibraryPrivate.framework/Versions/A/PhotoLibraryPrivate does not (there is no directory called /System/Library/PrivateFrameworks/PhotoLibraryPrivate.framework)

sudo ls -ald "/System/Library/PrivateFrameworks/Photo"*

drwxr-xr-x 3 root wheel 102 11 Sep 2014 /System/Library/PrivateFrameworks/PhotoLibrary.framework

At this point, I have tried:

- resetting the SMC twice

- reinstalling the OS from scratch

- verified the HD (no issues)

- repaired permissions

The issue continues.

More information:

Found the following command, which reveals the name of the hibernate file (this file does not exist currently, though /var/vm does; it is likely created on sleep):

> pmset -g

Active Profiles:

AC Power -1*

More info:

The iMac will crash (shut down) if I select 'sleep' manually from the Apple menu.
