Application: ktp-auth-handler (0.7.80)
KDE Platform Version: 4.12.3
Qt Version: 4.8.6
Operating System: Linux 3.11.0-18-generic x86_64
Distribution: Ubuntu 13.10

The crash occurred when examining the Certificate from jabber.ccc.de. 
I changed the selection of the "Certificate chain" chooser, from "jabber.ccc.de" to "CA Cert Signing Autority"

md5 of the certificate examined: 0c41f22b8c679d70928dcfddf34f80c1

The crash can be reproduced every time.
