My Retina MacBook Pro is missing some icons suddenly! What happened? This happened after a wake from sleep. And rebooting doesn't solve the problem! Has anyone encountered this problem before?

Every item in the bar, for example Safari, has no previous and next arrows for the button, and Finder is missing sidebar icon.
I have the same problem with my Retina MBP (the 2.3 GHz model); after upgrading to the latest 10.8.2 (including the graphics update) and resuming from overnight sleep, all Apple applications (Safari, Finder, etc) are missing all icons from toolbar and menubar (see a screenshot).

This is second time I encounter the problem. At first time I did a clean reinstall of Mountain Lion (i.e. wiped the disk) and did not install the latest OS X updates. When I yesterday updated OS X (after a week), today the problem was back after resuming the machine from overnight sleep.

rm -rf'ing all files under /Library/Caches and ~/Library/Caches and rebooting did not help for me. I filed a bug report at https://bugreport.apple.com.

Update:

After reading this thread, I re-booted into safe-mode, then back to normal mode and the icons are now back. I disabled hibernation as a precaution, until Apple will fix the problem.
