Seems like Chanspy. I have such crashes once every two weeks. It could
be caused by having Monitor or Mixmonitor together with Chanspy on
same channel. There's new framework for all this - called audiohooks,
that should eliminate all those chanspy-monitor problems, and it will
be out in 1.4.18 (you can use SVN branch 1.4 for now)
