Today backup execution failed several times due to an error:

ystem.ArgumentException: Ein Element mit dem gleichen Schlüssel wurde bereits hinzugefügt.
   bei Duplicati.Library.Main.BackendManager.List()
   bei Duplicati.Library.Main.Operation.FilelistProcessor.RemoteListAnalysis(BackendManager backend, Options options, LocalDatabase database, IBackendWriter log, String protectedfile)
   bei Duplicati.Library.Main.Operation.FilelistProcessor.VerifyRemoteList(BackendManager backend, Options options, LocalDatabase database, IBackendWriter log, String protectedfile)
   bei Duplicati.Library.Main.Operation.BackupHandler.PreBackupVerify(BackendManager backend, String protectedfile)
   bei Duplicati.Library.Main.Operation.BackupHandler.Run(String[] sources, IFilter filter)
   bei Duplicati.Library.Main.Controller.<>c__DisplayClass16_0.<Backup>b__0(BackupResults result)
   bei Duplicati.Library.Main.Controller.RunAction[T](T result, String[]& paths, IFilter& filter, Action`1 method)
   bei Duplicati.Library.Main.Controller.Backup(String[] inputsources, IFilter filter)
   bei Duplicati.Server.Runner.Run(IRunnerData data, Boolean fromQueue)

Can I resolve this myself?
