I have exactly the same problem. Whever I open string.xml and some other xml files I also get a Java Null Pointer error. Typing even a single character triggers it.
I can look at them fine as xml, but Resources view is broken - the left hand pane has the thin lines that should connect the elements in the tree structure, but no elements listed. Saving the file also creates null pointer errors. You can use editors that don't have a graphical view in the left hand window - for example the xml editor works fine. Unfortunately the more useful editors all show heirarchies and don't work. It is true even for the default files created by new -> android project. As I say, the xml itself looks fine; its related to how the information is shown in the left hand window; if it uses a tree representation of the data, it throws a Null Pointer exception.. Whatever it is, its a PITA. I would completely remove and re-install the whole devel environment if I was sure it would fix it.
