DaveM should be looking at this, related to bug 229610.
The problem was that we were trying to determine the default encoding from the parent file. However "/" doesn't have a parent - hence the null pointer exception. In the case where the parent is null, we'll use the subsystem remote encoding.
Why do we need to look for the parent, when the resource kind is a folder? Shouldn't a folder's encoding be specified by itself, rather than looking at the parent? Actually I don't even understand why we need to look at the parent of files, shouldn't they have an encoding specified by themselves?

We're looking at the parent to determine what the file/folder would default to if the user chooses to not explicitly specify an encoding.
I see. Makes sense, thanks.
