Patch: FYI: minor Class improvement

[Tom Tromey <tromey at redhat dot com>]

I'm checking this in on the trunk.

There were a few places in Class that threw an exception without a
descriptive message.  This makes it harder to figure out what has gone
wrong.  (In the early days, this was how we did things.  Nowadays we
can do better.)
