GTK Problems: Sidebar not Working, GUI Randomly Hangs

[soldier9599]

Linux: 4.8.4-1-ARCH x86_64
Deluge: 1.3.13+2+g6c73105-1
Xorg-server: 1.18.4-1

Ever since the recent update, the GUI has stopped functioning properly. The sidebar never works at all. It is just a blank region on the screen. I can hide/show and resize it, but it remains empty. I am forced to view all torrents at once. Occasionally, the GUI will become unresponsive for no apparent reason. The daemon continues functioning just fine, and all I have to do is terminate and restart the GUI.

I get this stack trace as soon as I start deluge-gtk. This is just for a plugin, so I'm not sure it's relevant, but it's some kind of gtk problem, so maybe.

[ERROR   ] 19:43:52 pluginmanagerbase:146 Unable to instantiate plugin!
[ERROR   ] 19:43:52 pluginmanagerbase:147 cannot import name DISPLAY_NAME
Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/deluge/pluginmanagerbase.py", line 144, in enable_plugin
    instance = cls(plugin_name.replace("-", "_"))

    from gtkui import GtkUI as _plugin_cls
  File "build/bdist.linux-x86_64/egg/prioritize/gtkui.py", line 45, in <module>
ImportError: cannot import name DISPLAY_NAME

I am also provided with this immediately when I start Deluge and then repeatedly with a constant frequency of about once every two seconds for as long as the application is running. Occasionally the key is a different image file, but it's throwing basically the same error every time.

Unhandled error in Deferred:

There are no known changes in Deluge code that would cause these. I would suggest you open a ticket with Arch, have you tested with previous versions?
