Bug description:
  Hi,
  I installed the MIDI driver for the hercules consoles and tried to work with them with the beta2 (r3623). When I go the options menu it seems to detect the controller because I can choose it. Then I click the checkbox "Aktivieren" (activate) and the the "ok" button. It crashes immediately. Heres is the output of the terminal.

  Xubuntu 12.04
