Message with no fields in .proto cannot be decoded

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Write .proto file which includes a message with no fields.
2. Compile the .proto file.
3. Attempt to decode any stream using that no-fields message.

The result: a "missing required field" error always occurs, even though the 
no-fields message doesn't have any required fields.
