Application: kleopatra (2.2.0)
KDE Platform Version: 4.12.5
Qt Version: 4.8.6
Operating System: Linux 3.14.7-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I clicked "Lookup Certificates on Server", searching "Gael", and then it crashed.

However it worked when I searched with other strings, such as "jdh8" and "Jitse".

The crash can be reproduced every time.

-- Backtrace:
Application: Kleopatra (kleopatra), signal: Segmentation fault
