After the deployment of SP2 I see a lot of these messages;

Could not save bundle state: System.IO.IOException: En fil, som allerede findes, kan ikke oprettes. ved System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) ved System.IO.__Error.WinIOError() ved System.IO.File.Move(String sourceFileName, String destFileName)

It shows up as an error, but if I check the application it is installed and working just fine. So all in all that's a good thing, but it generates a lot of unwanted errors in the zone... so any suggestions on how to get rid of this?
