That should be the right invocation. There may be a bug in the `extra_argv`
handling in runtests.py. It looks like it's stripping off one of the two
dashes, which doesn't look quite right.

If it works with

    python -c "import scipy; scipy.test(extra_argv=['--full-trace'])"

then it should work with runtests.py as well (unless there's a bug as
mentioned above).

Cheers,
Ralf
