Black Notification update window due to flashplugin-update error

[Carlos]

Everytime I start a new session I get an update notification icon on system tray. Whenever I click it a horizontal black window without window decoration appears in the middle of the screen.

After disabling destkop-effects I see a weird error description (it is written in many languages and the sentence seems to be cut) wich points to an error due to flashplugin-installer (see attached screenshot).

I have removed such package by doing "sudo apt-get remove flashplugin-installer" and the problem persists.

The problem appears from the very first day (Fresh installation of kubuntu 12.04 LTS ) and even after having upgraded KDE to 4.8.3 from backports ppa.

I've seen other users who are having the same problem here: http://forum.kde.org/viewtopic.php?f=67&t=101848&p=221503

The problem persists after having purged flashplugin-install package. I have changed window screen and I have just realized that a button appears. After clicking on the button a new konsole appears wich causes an error (see attached screenshot)
