Comment 7 for bug 827049

I think the problem can be reproduced as follows:

1. Open the home folder by clicking on the home icon in unity.

2. Try and drag'n'drop a folder to the sidebar.

If you tried to drag it anywhere but the bookmarks subsection of the sidebar, the folder zooms back whence it came and isn't added to the bookmarks. (It would certainly be more user-friendly if it were added to the bookmarks instead.)

If you tried to drag it to the bottom of the bookmarks section, ie under the last listed bookmark, it also zooms back whence it came is isn't added to the bookmarks. It *should* be added to the bookmarks. I think this is also the default case for a brand new user, who has no bookmarks by definition and therefore cannot add one.

If you drag it across to elsewhere in the bookmarks section, it is added. And at that point you can also drag another folder to the very bottom of the bookmarks section, ie it starts to work.

Closing the nautilus window and re-opening it causes the same issue as above.
