node is using public access role based protection but getprotectiontype returns notprotected

Hi All,

I'm filtering some search results based on protected nodes and came accross something strange:

if (!Access.IsProtected(currentNode.Id, currentNode.Path) || Access.GetProtectionType(currentNode.Id) == ProtectionType.NotProtected)

is this instance Access.IsProtected is true but Access.GetProtectionType returns NotProtected..

any thoughts as to why this would occur?
