I was just hitting the following when clicking on Behavior in the class browser.

Hello Holger,

Not reproducible on the current git version. Do you use 0.0.1? Could you please try with the git snapshot?

This was with 8815d3c61dfc04d539c8bcc676d35fb1d568698c and sure it is difficult to show that something is not there. I have moved to GST master for my main development now (I used 3.2 before).
