Right-click on commit list in empty Git Browser shows MessageNotUnderstood: UndefinedObject>>loadedHistorian

[j4yk]

Decided to try loading the Git browser since I'd never noticed it before. Menu click on the top-right pluggablepanel results in the dnu because the 'projectSelection' is nil and Boom! Probably a trivial fix but since I don't know the intent of the tool I'd prefer not to mess with it.
