Hi! Did you restart your session between the crashes? As this bug occurs in some dbus it might be a protocol change - I saw a similar backtrace when I upgraded gvfs - except in was in gtk filechooser using applications.
Do you know whether this bug already occured in 4.3.1? WM -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
