Release candidate bug with run entry point

Hi Blend4web staff.
I was trying the latest release candidate and I found what to me seems a bug.
I have attached a test project. Using logic nodes I created a node to be run with javascript ( api command run_entrypoint) . The first time it runs ok, the second it produces an error which you can see in firefox/chrome/safari debugger and the scene get stuck. With the previous releases it worked fine.
Cheers

Thank you for the report! Will be fixed!
