[Sidefx-houdini-list] two keyframed expressions on a single parameter

I think that the keyframes have always been the first frame of a given
scene. So it would appear that I was doing dev work in a scene that started
on frame 1 and then frame 17. Eventually I would find that my expression has
been saved as two separate keyframes on each start frame. I am not able to
reproduce this simply by changing the start frame, though. Lately, almost
all of my expressions have been python, but I'm pretty sure that I've had
this happen with hscript expressions too.
On this show, we have been staying with the same version of houdini through
90% of production. I'm sure that most of the otls that have exhibited this
have been developed in the same version of Houdini.
I will see if I can dig up an old version of an otl with two expressions
when I get to work.
