After this commit from @piotras it doesn't crash on the first button press, but does crash on the second. Backtrace:

I think the problem is not the second button, the problem are on all buttons.
You example crash on repeated click on any button, too.
The same on my programm.
If I click on the pdf button, the function generate_pdf dosn't work correctly and my app crash on the second click.
pdf_button.on("clicked", function(){
generate_pdf('test.pdf');
});
If I change "generate_pdf('test.pdf');" to a simple console.log, my programm works fine.
I think anything is wrong with the button-signal.
Maybe gir think the function is finished and delete anything before he is finished?

Its very crazy, I have a gtk-program with 2 buttons. The first create a string and run exec, the second create new gtk.widget's. If I click on any button, my program is crashing, but If I comment out the first on-clicked function, my programm works.. So my program are only working if I have not more than 1 on-button-clicked-signals and I run only 1 function they is a non-gir function or I run only gir-functions (more or less).
I hope this is helpful.

Crash is caused by exception being thrown in callback. This exception is completely silent. In case of guitar example,you can add try catch block:
try {
return pipeline.set_state(gst.State.PLAYING);
} catch (err) {
console.log(err);
}
It doesn't solve the problem, but at least crash goes away and we have proper human readable message.
I am investigating it, cause for some reason playing state is introspectable as interface. Which is obviously wrong as it's enum.
