Unclear what is happening. It probably has to do with a resource file being out of date or corrupted at the point we are trying to retrieve it. But the builder should be more tolerant to such errors and silently absorb the shock (and pretend the offending file wasn't there). Need to investigate.
The new builder catches resource out of sync problems & converts them into markers so the user knows to refresh then rebuild the project.
