cliking on pidgin's contact list opens the notification pannel for peripherals in kde

[manchette]

Hello,
you may be able to help me understand this matter : each time i click on 
the contact list of pidgin 2.10.7 it opens the notification pannel for 
peripherals in KDE.
The pannel is empty and says that 'no peripheral is available'.
Is this due to too many events being catched ? Is this due to KDe or 
Pidgin , how can i trace and solve this ? Thanks
I'm using openSUSE 13.1 and KDE SC 4.12.0
