           Summary: Crash in position provider plugin on startup
           Product: marble
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: marble-bugs at kde.org
        ReportedBy: bbeschow at cs.tu-berlin.de


Application: marble (PRE 1.2 SVN)
KDE Platform Version: 4.5.4 (KDE 4.5.4)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-ARCH i686
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I updated sources from SVN, recompiled Marble, and started it.

- Reason:
The crash is caused immediately during startup due to
PositionMarker::ui_configWidget being 0.

The crash can be reproduced every time.

-- Backtrace:
Application: Marble Virtual Globe (marble), signal: Segmentation fault
