topic: use more protective code to access publishing code

There are some code path where the operation is not properly initialized and
lack the new attributes. While the lack of initialization, is suspicious and
I've not be able to pin point case where this happens.

Currently the code crash when it encounter this situation. So we make the code
more resistant to this case to prevent bad user experience.
