Application: kontact (4.13 beta3)
KDE Platform Version: 4.12.95
Qt Version: 4.8.6
Operating System: Linux 3.13.0-19-generic i686
Distribution: Ubuntu Trusty Tahr (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
kontact autostarts with the session begin. it asks everytime to migrate notes to the new backend. this pop-up opens up up twice. on the first one started the migration. the second one i aborted. the kontact window appears with an empty kmail-layout.

- Unusual behavior I noticed:
every time kontact starts, it ask for mirgation of notes. and shows two dialagos for the migration.

- Custom settings of the application:
i have a windows setting rule that kontact only shows up on an fourth workspace. this rule gets ignored and it shows up on the workspace i usually start with, the first one.
When i close the appliction and start it again appears on the workspace on the right (fourth) workspace.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
