Bug#886861: ring: abort with assertion failed: (_gtk_rbtree_is_nil (tree->root))

[Petter Reinholdtsen]

Package: ring
Version: 20161221.2.7bd7d91~dfsg1-1
Severity: important

The gnome-ring client keep crashing on me.  Here is from one example run
when it crashed.  I've removed the address I tried to call.  Calling is
not required, normally it crash when I search for people in the list of
contacts.
