webapi pagedresult failes when using $expand

Question

To get the inline count in odata style from a webapi2 controller I read on this page: http://www.asp.net/web-api/overview/odata-support-in-aspnet-web-api/supporting-odata-query-options that I should return a PagedResult from my method. I made my method in my apicontroller like this:

public PageResult<Software> Get(ODataQueryOptions<Software> options)
    {

        ODataQuerySettings settings = new ODataQuerySettings()
        {

        };

        IQueryable results = options.ApplyTo(db.Software, settings);

        return new PageResult<Software>(
            results as IEnumerable<Software>,
            Request.ODataProperties().NextLink,
            Request.ODataProperties().TotalCount
            );
    }

This works fine for request like this:

http://dummy.com/api/Softwareapi?$inlinecount=allpages&$filter=Deleted%20eq%20false&$orderby=SequenceNo&$top=7&$skip=0

But for a request like this:

http://dummy.com/api/Softwareapi?$inlinecount=allpages&$filter=Deleted%20eq%20false&$orderby=SequenceNo&$top=7&$skip=0&$expand=Supplier

I get:

    <Error>

If I use quick-watch feature in the vs debugger I can see results has the correct amount of items and those items have suppliers, but I cannot seem to get pagedresult to see that.

Does anybody here want to help me with this?
