"Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges"..."Request failed"

When I tried running some code within the "Microsoft.SharePoint.SPSecurity.RunWithElevatedPrivileges" block I received this exception message:

System.Security.SecurityException was unhandled by user code
Message="Request failed."
Source="Microsoft.SharePoint"

InnerException:

It turns out the problem was I was executing this code too early in the page life cycle. I moved the block to "CreateChildControls" and the problem went away.
