Seen in 10.9.0 beta1 * Create files a.txt and b.txt in folder Photos. * Mark b.txt as favorite, (but not a.txt) * Visit Favorites page, and try rename b.txt to a.txt, as expected an error message is shown. * The error message has the wrong folder:  no file a.txt exists in /, and if so, that would not be the cause of the collision. Expected behaviour: The name "a.txt" is already used in the folder "Photos". Please choose a different name.
