Application: kded4 (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:
Booting up my system which automatically starts KDE, current kubuntu

- Unusual behavior I noticed:
the graphical display requesting a LUKS password/passphrase did not appear, i got a simple text message instead.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
