Status changed to 'Confirmed' because the bug affects multiple users.

are you using extensions which have css stylesheets? there was a crash that is fixed in 3.8 but may need backporting to 3.6

https://git.gnome.org/browse/gnome-shell/commit/?id=655dce6a4b2d5ad02a3e108b6fbc118f4a3ae2d2

Yes most of the extensions that I'm using have their own css files:
https://extensions.gnome.org/extension/17/dock/
https://extensions.gnome.org/extension/442/drop-down-terminal/
https://extensions.gnome.org/extension/559/quit-from-dash/
https://extensions.gnome.org/extension/474/stopwatch/
https://extensions.gnome.org/extension/162/todo-list/

I'm not certain when the crashes started but looking at the date of the
commit that has introduced the css bug I'd say that it is quite possible
that this is the reason.
