[ubuntu-mono] [Bug 582007] Re: Docky randomly crashes, usually after my laptop has been suspended

[^rooker]

Sorry, for posting on an old issue, but it seems to be getting worse :(

On 12.04, Docky only used to close/crash when installing new packages.
Since 14.04, it disappears every few minutes.
On 16.04.1, Docky won't even start anymore :(

Docky version (Xubuntu 16.04.1): 2.2.1.1 Release

Bug description:
  I seem to get this quite a bit lately.  As far as I can tell it
  (mostly) happens after I resume from a suspend.  But not every time...

  Exception in Gtk# callback delegate
    Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
  System.NullReferenceException: Object reference not set to an instance of an object
