eidogo.Player.showComments is not defined.

[metaperl]

When I load my game into eidogo via this URL:
http://eidogo.com/#url:http://online-go.com/api/v1/games/938171/sgf

and then open the Chrome Developer Tools, the console yields this stack backtrace:

Uncaught TypeError: undefined is not a function
eidogo.Player.showComments 
eidogo.Player.execNode
eidogo.Player.refresh 
eidogo.Player.goTo 
eidogo.Player.load
eidogo.SgfParser.init
eidogo.SgfParser

On Mozilla Firefox, I get: TypeError: _13f.replace is not a function

On Safari, the call to .showComments() leads to this error:

TypeError: undefined is not a function (evaluating '_13f.replace(/^(\n|\r|\t|\s)+/,"")')
