Unable to start deluge after upgrading to kernel v3.16.3-2 - deluge-gtk: Cannot aquire lock

[OmegaPhil]

First boot in this Debian Testing system after upgrade from kernel v3.14.x to v3.16.3-2, attempting to run 'deluge' (1.3.7-1):

/usr/lib/python2.7/dist-packages/deluge/ui/gtkui/queuedtorrents.py:60: Warning: The property GtkDialog:has-separator is deprecated and shouldn't be used anymore. It will be removed in a future version.
  "glade/queuedtorrents.glade"))

  "glade/queuedtorrents.glade"))
[ERROR   ] 13:37:45 ipcinterface:158 Deluge restart failed: Couldn't listen on any:/home/omega/.config/deluge/ipc/deluge-gtk: Cannot acquire lock.

This is probably due to a glib upgrade (glib2.0 >= 2.41.2), as SpaceFM also had locking issues and needed to be fixed (​https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=763575).

Rating as blocker here as it completely prevents startup.

This is a known issue due to a unclean shutdown of GTK UI, you need to delete the dir /home/omega/.config/deluge/ipc.
