Comment 1 Marc-André Laperle CLA 2011-07-15 13:34:52 EDT 
Ah! I had modified the C++ File Template to contain only this: ${declarations}
Comment 2 Marc-André Laperle CLA 2011-07-15 18:42:14 EDT 
So, repro steps:
1. In Code Templates, edit Default C++ source template so that it contains nothing
2. Try to create a class using the wizard
Comment 3 Marc-André Laperle CLA 2011-07-22 13:32:23 EDT 
Fixed in 8.0.1 and master > 20110722
