F23, KDE, fully updated.
Everything works inside the File Manager, but if I rename a file on the Desktop then I can no longer access it after that. Example:
Right-click on Desktop, Create New --> Folder.
Name the folder "foo".
Click on foo, opens File Manager in foo directory. Close that.
Right-click on foo, Rename. "bar"
Click on bar... Error, dialog says, "Unable to run the command specified. The file or folder /home/alan/Desktop///foo does not exist."
(After reboot, clicking on bar works.)
Same thing happens with Create New --> Text File.
I don't use this machine often, but my wife tells me this has been happening for a long time. The problem manifests on both of our logins.
