This doesn't help. The following assert in trace.py raises
an AssertionError:
    assert filename.endswith('.py')

I've added print statements to find_executable_linenos()
and got the following:

<doctest _threading_local[7]>
Traceback (most recent call last):
   File "../../../trace.py", line 790, in ?
   File "../../../trace.py", line 787, in main
     results.write_results(missing, summary=summary, coverdir=coverdir)
   File "../../../trace.py", line 301, in write_results
     lnotab = find_executable_linenos(filename)
   File "../../../trace.py", line 420, in find_executable_linenos
     assert filename.endswith('.py')

So what is <doctest _threading_local[7]>?
