Could you please tell us a few easy steps in order to reproduce the bug?

[Dmitry Shachnev (mitya57)]

AFAIR that time it crashed when I started gnome-shell from the Classic/Fallback session, but I can't reproduce it now.

[Pedro Villavicencio (pedro)]

do you consider the issue fixed then?

[Dmitry Shachnev (mitya57)]

OK, I will reopen it if i get it again.
