Sorry, backtrace is about an crash with wnck applets. so your descrition isn't helpfull. Can you check if /run/user/1000/dconf/ is writeable for user 1000 if it happens?
no user response!
I've gotten the same crash. It happened after I dragged an icon on the taskbar to a different position. I'm not able to reproduce it immediately afterwards, now that the toolbar has restarted.
