New crash information added by DrKonqi

kactivitymanagerd (1.0) on KDE Platform 4.8.1 (4.8.1) using Qt 4.8.0

This crash occurs when logging in to KDE 4 (every time)
It might be linked to another segfault with Kmix, which comes first and is raised as a duplicate of this lead ticket https://bugs.kde.org/show_bug.cgi?id=290742
