--- Comment #5 from pyfisch@googlemail.com --- Sorry, I did not see that it should not be fixed by normal users. I uploaded a patch with my already done work (converting add_text.py) to this bug. https://gerrit.wikimedia.org/r/#/c/94623/
I am myself a student, so I could participate in Google Code-In and solve it there. :-P
