Are you sure it's from RPMFusion ?
I do not find it there.
Your example (one curly brace and cursor after it) works for me as you expect it.
The example from the old thread you linked to (two curly braces and the cursor between both), does not work.
But the autocompletion (type the left brace and get both and the cursor placed with indentation in the line between them, like ollydbg's example) works fine here.
Code::Blocks from my copr (see signature).
Official repo has 16.01, can you try a nightly build from my copr and see if it works better ?
Do you have the smart indent plugins installed? They are part of the contrib plugins package.
