           Summary: nrwt failing with worker/ raised UnicodeDecodeError
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dgrogan at chromium.org

This seems to only reproduce on one of my branches, so I've probably introduced an error that interacts badly with the recent nrwt changes.  Though I have no changes in Tools, just Source. Dirk, if you could try to glean some hints about a possible nrwt bug from this stacktrace, I'd appreciate it.
