ok I can reproduce it now (8.04 with all updates applied). it happens only once per session. if I log out and in again, the error can be reproduced again.
open two different local folders nautlius. drag a file from the right window to the left, when the cursor passes over the places list and touches the networkserver entry, the drag&drop event is stopped and I get the following error (note: I did not want to place the file on the network!) Error while copying "test.jpg". There was an error copying the file into network:///. (Show more details..) Operation not supported by backend. and in another case last week I had a similar error while dragging a file from the desktop to a local folder in nautilus: There was an error creating the folder "test".
