Package: vnc4server
Version: 4.1.1+X4.3.0-21
Severity: normal
Steps to reproduce:
1) vnc4server :9 -depth 24 -geometry 1024x768
2) xvnc4viewer localhost:9
3) press F8, disable "auto select" and set hextile with 256 colors
4) apt-get install freecol in a debian unstable chroot
5) wget http://iki.fi/lindi/freecol/lindi_Hollanti_1639_2_syksy.fsg
6) start freecol inside chroot so that it talks to vnc4server outside chroot
7) load the savegame
8) choose "show grid" from the view menu
Expected results:
8) grid of the map is shown
Actual results:
8) vnc4server segfaults.
