[Interest] unhelpful error from QFile loading non-existent resource

[Matthew Woehlke]

If I do something like:

  QFile f{":/does/not/exist"};
  f.open(QFile::ReadOnly);

Obviously, it fails. However, QFile::errorString returns "Unknown
error". Is there a reason for this unhelpful message as opposed to
something like "Resource not found"?

(On a loosely related note, what happened to my old bug reporting
account? I don't seem to be able to log into the new qt.io site. Have
all bugs that I'd previously filed just gone missing?)
