Version:           0.6+svn837399-1 (using KDE 4.0.98)
Installed from:    Debian testing/unstable Packages
OS:                Linux

Steps to reproduce:
1) wget http://iki.fi/lindi/marble/sid-marble.complete
2) qemu -hda sid-marble.complete -boot c -snapshot -m 256 -redir tcp:5924::5924
3) wait for the testcase system to boot, this may take up to 5 minutes on a fast computer
4) (qemu) login as root/root
5) (qemu) dhclient eth0
6) (qemu) vnc4server :24 and enter any password you like
7) (qemu) DISPLAY=:24 marble
8) (host) xvncviewer localhost:24 and try to rotate the map

Expected results:
8) Map is rotated

Actual results:
8) marble segfaults and kernel prints

marble[1993]: segfault at 1c ip b74a8dfc sp bf9dab68 error 6 in libQtGui.so.4.4.0[b7270000+8cc000]


More info:
1) I included a complete qemu qcow2 disk image to reproduce the issue since other people were unable to reproduce it on their systems.
2) gdb shows the following backtrace:
