nit: This probably isn't necessary, but you can leave if you like, I guess. 
Maybe change to DCHECK_EQ?

[Eric Dingle, 2012/01/30 18:27:11]

Done.

Is this cleaned-up with ~result or does it leak?

[Eric Dingle, 2012/01/30 18:27:11]

It's cleaned up by ~result. Added a comment.

+  extension_data->SetString("id", extension_->id());
+  extension_data->SetString("name", extension_->name());
+  extension_data->SetString("version", extension_->version()->GetString());
+  extension_data->SetString("description", extension_->description());
+  extension_data->SetString("icon", icon.spec());
+
+  DictionaryValue result;
+  result.Set("extension", extension_data);
+
+  web_ui()->CallJavascriptFunction("extension_activity.handleExtensionData",
+                                   result);
+
+  ExtensionActivityLog::GetInstance()->AddObserver(extension_, this);
+}
+
+void ExtensionActivityUI::OnExtensionActivity(
+      const Extension* extension,
+      ExtensionActivityLog::Activity activity,
+      const std::string& msg) {
+  DictionaryValue result;
+  result.SetInteger("activity", activity);
+  result.SetString("message", msg);
