Application: k3b (2.0.1)
KDE Platform Version: 4.5.80 (4.6 Beta1)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-5-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Every time I try to open K3b it crashes, if opened in terminal this is the message I get: 

KGlobal::locale::Warning your global KLocale is being recreated with a valid main component instead of a fake component, this usually means you tried to call i18n related functions before your main component was created. You should not do that since it most likely will not work 
K3bQProcess::QProcess(0x0)
kde(10471): Communication problem with  "k3b" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.ServiceUnknown" : " "The name org.k3b.k3b was not provided by any .service files" " 

KCrash: Application 'k3b' crashing...

The crash can be reproduced every time.
