Muon notifier doesn't notify about updates available

[Gannet]

How to reproduce the bug:
1. Run sudo apt-get update.
After command is completed there are no notifications about updates available appears.

2. Run Muon - Configure Muon Manager.
3. Push "Defaults" button and then "OK".
After that notification icon appears in tray. But next time when updates are available I must repeat steps 2 and 3 to get an notification.

When I'm starting muon from Konsole and trying to check for updates, a several messages appears:

~$ muon

The same problem even with version 11.10 on all my machines with Kubuntu. I just drew her attention, and updated from the command line or run Mon and check for updates manually.

Maybe the output of these commands with Kubuntu 11.10 will help in solving the problem.

When I installed Muon-git from PPA it started notify about updates. Now, when Muon 1.4 released and I installed it there is no notifications again ! I came back to Muon 1.3.1 but no notifications too ! The one thing I've found is error appears when I'm starting muon-updater (in logs):
