Errors in SQL Server 2005 Profiler

I notice this running the SQL Server Profiler under the application name Report Server. Every time it runs, it reports an error (in the Error field of Profiler). Does anyone know what this is?

declare @.p1 nvarchar(64)
set @.p1=NULL
exec GetDBVersion @.DBVersion=@.p1 output
select @.p1

Do you mean when running Reporting Service (or just an application named Report Server?), you found errors with the statements you post? If you're talking about Reporting Service, take a look at this post:
