I am trying to run grass 7 commands through the processing toolbox, but I am getting the following error:

An error has occured while executing Python code:

I have submitted a patch yesterday that was already committed. You need the latest master code (or wait for 2.4).

• resolution was changed from to fixed/implemented

I just updated QGIS master QGIS version: 2.3.0-Master Master, d7bd9c7), but I am still getting an error when trying to run a grass7 command:

try delete the folder

/home/paulo/.qgis2/python/plugins/processing

and restart qgis (and do not update processing if it asks you to do so).

Brilliant, that did it... only got the message "Grass7Algorithm instance has no attribute 'grass7Name' See log for more details", but only after the expected function output. Great!
