This error usually appears when a desktop notification is dismissed/clicked on.
See if clicking or dimissing a desktop notification generates that exception. In any case, it's not an opensnitch functionality error, but python3-notify2' package:
File "/usr/lib/python3/dist-packages/dbus/connection.py", line 232, in maybe_handle_message
File "/usr/lib/python3/dist-packages/notify2.py", line 154, in _closed_callback
Confirmed that it is caused by clicking dismiss notifications on the desktop.
This was a bug in python3-notify2 package. Debian distributes version python3-notify2 0.3-5
which doesn't handle exceptions when closing notifications:
152 def _closed_callback(nid, reason):
153 nid, reason = int(nid), int(reason)
154 n = notifications_registry[nid]
155 n._closed_callback(n)
156 del notifications_registry[nid]
This was fixed on version 0.3.1: https://bitbucket.org/takluyver/pynotify2/commits/d4482e7169e3e9787d602d78f55c0cd74d805ff6
I'm seeing a number of errors in the shell where I started opensnitchd and the UI of the form:
Traceback (most recent call last): File "/usr/lib/python3/dist-packages/dbus/connection.py", line 232, in maybe_handle_message self._handler(*args, **kwargs) File "/usr/lib/python3/dist-packages/notify2.py", line 154, in _closed_callback n = notifications_registry[nid] KeyError: 160
The KeyError appears to increment. The rest is always the same.
It seems to trigger some of the time when I create a new rule in the UI as a response to something trying to open a connection. It is a small percentage of the time. I have not been able to find a pattern.

To Reproduce The errors seems to trigger some of the time when I create a new rule in the UI as a response to something trying to open a connection. It is a small percentage of the time. I have not been able to find a pattern.
Looking at the logs, all I see are entries for "Added new rule", and some "Saved new rule". There are no errors.
Possibly related: Some of the forever rules seem to get lost every few days. (IP related?)

Anything I can enable to get you better debugging info? (Explicit instructions please.)
