System-Testing app crashed on clicking next button after submitting the test

[neonatus]

Binary package hint: checkbox

After finishing the tests and submitting the report there are two buttons in the window. One is labeled "previous" the other "finish". After I click on the finish button it changes it's label to "next". And everytime you click it you get the error in console saying:
Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/checkbox_gtk/gtk_interface.py", line 161, in on_dialog_response
    gtk.main_quit()
RuntimeError: called outside of a mainloop

But the program itself does not exit until you kill it by pressing ctrl+c on the console command you started it with.
