Clicking the "Add section header" on first quiz page, I am getting a fatal error:

We are using Moodle 2.9.2 which was upgraded recently from Moodle 2.7.2 (and over the years from version to version)
So it is not a clean Moodle 2.9 install.
And I think we have some legacy non empty mdl_quiz_sections table with rows like:
id, quizid, firstslot, heading, shufflequestions
|
"256","446","1",,"0"
|
"512","914","1",,"0"
|
"768","1340","1",,"0"
