why this change?

Because OpenItem() function used to send path.DirName(), but now it sends  full
path with the file name inside. 

OpenItem(profile, full_path.DirName(), OPEN_FOLDER,OpenOperationCallback()); ->
OpenItem(profile, full_path, OPEN_FOLDER,OpenOperationCallback());	

If there is (base::DirectoryExists(path) != (type == OPEN_FOLDER), then
OPEN_FAILED_INVALID_TYPE is called.

Sorry, but VerifyAndOpenItemOnBlockingThread(), basically OpenItem()'s
implementation, is used in many places. You can't just change it to suit your
own needs without considering the other callers.

Likely ShowItemInFolder() can't just simply reply on OpenItem() anymore.

I'd suggest ShowItemInFolder() first try to figure out if the file manager is
Nautilus. If it is not, then do the current behavior and ShowItemInFolder() for
the folder. For Nautilus, do something else.
