Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    Ubuntu Packages

Whenever I login to my Kubuntu 8.10 and the KDE session is being restored, kontact crashes with an SIGSEGV. This does not happen if I start Kontact manually afterwards.

Backtrace:
Application: Kontact (kontact), signal SIGSEGV
