I got this Traceback with a notebook based on Sage 5.9:

G = matrix([[2 for u in (1,..,21)] for v in (1,..,21)])
print G
Traceback (most recent call last):

    framelist.append((frame,) + getframeinfo(frame, context))

    lines, lnum = findsource(frame)
  File "/waste/cn/sage-5.9/local/lib/python/", line 528, in findsource
    if not sourcefile and file[0] + file[-1] != '<>':
IndexError: string index out of range

The code works as expected in a Sage shell.
