Title: test that the printed stacktrace is informative in case of failure

in former versions, the printed stacktrace could be empty due to erroneous
cleanup in proper. This test prevents this to happen again

This complements the already merged pull request 36 and could be potentially extended to do other kind of output checking.

The way of doing the test is a bit hackish, though, but is a quite clean way to do tests on side effects, thanks to the nice abstraction on printing proper has implemented
