replace string with "Exception expected".
The e.error.toString().contains below checks for "Invalid arguments" with a
capital "I", and therefore would never match, but just to make it even more
obvious that we don't want to catch this error below.

[Mads Ager (google), 2013/01/09 09:29:14]

Done.

[floitsch, 2013/01/09 09:12:59]

Alternatively you could use "test: (error) => error is FileIOException" (as
named argument to catchError).

[Mads Ager (google), 2013/01/09 09:29:14]

I find this more readable since I want to check more and don't want to combine
it all to one boolean.

add a receive-port to make sure the test is run.
