Yes, as Tony said. I believe Chrome simply accepts whatever permissions settings you have in your destination folder.
In this specific case, your permissions settings in "Desktop" folder must be such that every file/folder in it inherit the "Desktop" permission settings. Are they set like that?
Now that I think about it, however, I wonder in what permissions context Chrome runs. It should be yours, and so YOU should be definitley one user able to open downloaded files! This doesn't seem right, unless Chrome is running under some other credentials than yours?! That, ye, may be Chrome bug you just found.
