For those of you who are having trouble with this. I have received the confirmation that the hotfix request has been accepted by the developers and a hotfix is on the way. Because we are planning to migrate to SQL Server 2005 we have chosen to request the hotfix for Reporting Services 2005.
As soon as I receive information about the hotfix I will let you know.
I have received the hotfix and will probably be testing it next week. The hotfix only solves the Report Manager side of the problem since the Visual Studio side of it has to be fixed there. There is no hotfix planned for Visual Studio 2005 but "it will be fixed in the future" was the answer to my question.
