One last comment: I tried downloading upstream pygobject 3.20.0 (which was released two days ago), and the scopes run fine using the Xenial typelib.
So I think the underlying problem is that we've got a problem of version skew, with the versions of gobject-introspection and pygobject currently in Xenial being incompatible. We either need to downgrade gobject- introspection (and rebuild typelibs for any affected packages), or upgrade pygobject. ** Also affects: pygobject (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1538471 Title: scope-runner-dbus.py assert failure: *** Error in `/usr/bin/python3': free(): invalid next size (fast): 0x0000000001ca17b0 *** To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntukylin/+bug/1538471/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
