Google Chrome: lock contention for shared file list item 0x7fe0f6a56790

Any time I try to save an image using my google chrome browser I get this error message when checking my console:

10/9/15 9:26:16.600 AM Google Chrome[228]: lock contention for shared file list item 0x7fe0f6a56360

10/9/15 9:26:16.601 AM Google Chrome[228]: lock contention for shared file list item 0x7fe0f6a56790

What does this mean and how do I fix it?

Thanks for your help!
