If you can reproduce this crash, please try to find the kded module which causes the issue. For more information, please see http://kdepepo.wordpress.com/2011/05/11/troubleshooting-kded4-bugs/
Comment 2 razermoko 2014-01-12 09:50:41 UTC 
Hi Christoph,    I am a novice user in Fedora, before that i used ubuntu quite some time. Ya, I can see the problem evretime when i enter the USB CDMA modem and try to check the "Mobile broadband enabled". It goes off and then after 1 or 2 seconds its back to normal but if i again try to check the mobile boradband option then it happen again...(BTW first time i fill the settings for dial-up connection like username, password after done the settings its same behaive).
I thing the problem is connecting Dial-Up through Mobile Broadband(USB Modem).
One Thinng I say it not only in KDE version it also exist in Gnome DVD version of Fedora as well.
