Reported using DrKonqi
Comment 1 Christian Trippe 2014-12-26 19:50:58 UTC 
No idea why DrKonqi choose th product "KDE", I guess systemsettings is more appropriate.
Comment 2 Christoph Feck 2014-12-30 02:42:54 UTC 
Crash caused by KIO uri filters, maybe Internet Keywords.
Comment 3 Hrvoje Senjan 2015-02-01 19:08:33 UTC 
*** Bug 343634 has been marked as a duplicate of this bug. ***
Comment 4 Eike Hein 2015-02-02 14:25:42 UTC 
Please give more exact steps to reproduce:

1. The exact sequence of actions
2. The patterns you enter.
3. By "confirm" do you mean the subdialog or the module Apply button.

Created attachment 90876 [details]
Screenshot of the mentioned dialog

1. open systemsettings -> shortcuts -> web shortcuts
2. press the new button and fill out the dialog (Name, link, shortcut) (see screenshot)
3. press "OK" in the dialog from 2
4. systemsettings crashes

Requesed information was provided
Comment 7 Eike Hein 2015-02-02 19:20:14 UTC 
Thanks! After testing with the above, it appears that a fix I made on Jan 8th has inadvertendly also addressed this crash. Unfortunately it was committed a few days too late to make the Frameworks v5.6 release (I can reproduce the crash on v5.6). It will be included with the Frameworks v5.7 release on February 12th.
