[Traverso-devel] Crash in current git code

[ben levitt]

Hi Remon,

I know it's been a while...  :)  I hope all is well with you!

I'm finally playing with the latest git code.  (My first time since
the move to git(!!).)  It looks great.

But I did noticed a crash whenever I hover the mouse over the TimeLineView.

Here's my backtrace.  I'm on a mac, running Qt 4.7, and portaudio.  It
looks like, in TimeLineView::mouse_hover_move_event(),
cpointer().scene_pos() is failing because the cpointer's m_port value
is NULL.  I don't remember where that is supposed to be set...

If you remind me how that is supposed to get set up, I can go looking
for it.  But I'm sure you could find and fix this faster than I could.
 :)

All the best!
Ben
