  Additional information for the SRU request:

  [Impact] Apparently random crashes of signon-ui when creting or re-
  authenticating accounts.

  [Test Case] Open Online Accounts, click on "Add account", choose
  "Google", then press "Cancel", then "Add account" and "Google" again.
  This sequence of operations might lead to a crash.

  [Regression Potential] The fix is entirely in the signon-ui process and consists of removing a widget pointer from a hash table when the widget itself is destroyed. Failing to do this was causing this bug, because signon-ui would try to use a destroyed widget.
  The patch itself does not touch other code paths than this, and we've been using it in saucy without noticing any regressions.

  The actual patch fixing this is http://bazaar.launchpad.net/~online-
  accounts/signon-ui/trunk/revision/86
