"Do we quit gtk_main" is alway printed!

I found another place where it hangs, I never notice it. It apppear also
when the user close a figure without leaving drgenius. I have been able
to trace back:

Program received signal SIGINT, Interrupt.

Does not help much. I try to suspect I have some memory leaks that show
up in the context of guile.
I will try to trace memory leak.
