           Summary: KMLTest Crashes with segfault on
                    GeoDataGeometry::detach
           Product: marble
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: unspecified
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: marble-bugs at kde.org
        ReportedBy: g.real.ate at gmail.com


Version:            (using Devel)
Installed from:    Compiled sources

The KMLTest ( marble_build_dir/tests/KMLTest ) is currently failing because of
a segfault in the GeoDataGeometry::detach method. 
I'm including the backtrace inline: 
Program received signal SIGSEGV, Segmentation fault.
