FATAL EXCEPTION:main from ListView and Adapter

I am getting the following error on my Android App. Up until about 20 minutes ago it was working fine.

In my GetView override method I have the following:

if (view == null) {
view = context.LayoutInflater.Inflate (Resource.Layout.saint_row, parent, false);
}

and obviously the view is an adapter.

I did change the above line from this:

if (view == null) {
view = context.LayoutInflater.Inflate (Resource.Layout.saint_row, null);
}

It worked for about 30 seconds then started throwing the exception again.
