How to reproduce (quite easy on my machine):

  • add a MIDI Input in Ingen
  • connect it in Patchage to something that produces MIDI events (like Active Sense event my keyboard sends twice a second)
  • use rubber band selection to select the MIDI Input in Ingen
  • press Delete
  • watch Ingen crash ;)

Note: all steps are important; the MIDI Input needs to be connected to an active event source (not just loopback port with no data flowing through it) and rubber band selection must be used (and not right click/Delete, which seems to work correctly).

Same problem as #192. Fixed in r1520.
