Hi

The ezsurvey module generates a debug notice on the /survey/list page (click "Survey" in top menu in admin):

Notice: Undefined index: contentobjtattr_language_code in /data/home/vl/work/QA/tests/cruisecontrol2/projects/ezp/source/.run/extension/ezsurvey/modules/survey/classes/ezsurvey.php on line 379

Steps to reproduce

Install ezpublish plain package
Install ezsurvey (Run survey's automatic setup wizard)
Create a survey
Resond to the survey using admin user
Click "Survey" in top menu in admin
If running xdebug, you'll notice the notice on top of the page.
If not running xdebug, you'll notice it in log files
