Comment # 3 on bug 915314 from David Liang

http://www.freedesktop.org/wiki/Draganddropwarts/

Recommendations:

    Use the correct URI syntax: 'file://host/path'. If no host is to be given
(illegal, but see Wart 2), the syntax should be 'file:///path'.
    Use \r\n at the end of each line.
    Use library routines such as gtk_selection_data_set_uris() to create
correctly formed lists for you. See the freedesktop.org File URI Specification
for more details

Not sure if it was a Nautilus bug, seems upstream sugguest we should append
'\r\n' at the end of each line.
But just as you said, the bug exists even in SLE11.
