Description

In the notebook, looking at the source of some methods ends with a Traceback and then the notebook keeps being busy until I interrupt the computation.

Steps to reproduce:

  1. Open notebook (tested on sage-4.7.2.alpha2 and alpha3)
  1. create matrix, e.g. (without the sage:)
    sage: m = random_matrix(ZZ,100);  m
    
  1. look at source of the determinant() method:
    sage: m.determinant??
    

It seems like the source formatter gets confused by the traceback in the method's docstring. See attached screenshot for illustration.
