Version:           1.3 (using Devel)
OS:                Linux
Installed from:    Compiled sources

I found two behavior:
a) When kontact is open with a new KDE session it chras with the backtrace bellow;
b) When kontact is open after starting a KDE session, it open kwallet (OK) and then crash... On the second try (with kwallet already open) it opens.

I'm using (KDE 4.1.96 (KDE 4.2 RC1))

Backtrace:
Aplicação: Kontact (kontact), sinal SIGABRT
