Crash if maxPanels < 2

[SerSmall]

Hello,
I get an issue, not a big deal but I wanted to share.

I get to use nuke with max panel setup to one, but sadly I figure it makes Stamps to crash (Nuke with it) but everything works well if the max panel is set to more than 2.

Stamps works fine for me with max panels set to one; I suspect something else in your setup is conflicting with Stamps.
