Invalid character in a Base-64 string

I sometimes get the error message "Invalid character in a Base-64 string - view state may be corrupted". The error occurs when trying to publish a page with a large view state-variable in edit mode. Anyone else who has experienced this, and, maybe even has a solution to the problem? I have only had this problem when the web server is behind a fire wall, so my guess is that the fire wall may be a part of it.

This problem is known to occur when protection against cross-site scripting has been enabled in the firewall. It is a generic ASPNET problem and the only solution, as far as I know, is to not enable the cross-site protection.
