"Make this test work"

Done.

I don't like this use of inheritance.  It's kind of confusing and would make
extending this test further difficult.

Having a separate test case to cover the new arg seems unnecessary.  Maybe just
add the script arg test into the existing test case?

[halyavin, 2012/05/25 09:37:45]

It will make extending it easier. All tests could extend NaClGdbTest. But we can
always separate the main part of test later if we need more that 2 tests.
