I had this problem on my retina with 10.7.5. I solved it by shutting down
Chrome.
Then go to Go and choose Go to Folder, paste this in:
~/Library/Application Support/Google/Chrome/
Rename the Default folder, Backup-Default.
Re-open Chrome.
Copy your bookmarks over to the new Default folder created from opening up
Chrome.
I think it's due to a corrupt user setting, so this creates a new user
profile for you.
Reverse if it doesn't work.
