Not a bug, but looks like severe usability problem to me.
When you're browsing the first level of other user's share and right-click a file or directory, it is possible to select "download containing folder" option, requesting downloading of the whole collection.
Assuming noone never wants to download the whole collection it would be very convenient if that option became disabled in context menu for the 1st level share.
