If you need help, you should try to use pristine Git, especially if it is
not obvious to reproduce.

Reproduced, analyzed and patch on the mailing-list.

You can avoid the segfault using "-draw_mouse 0". But that will not make it
usable for you: the VNC X11 server has a strange use of 32-bits color depths
(11+11+10 bits for RGB while the most common is 8 bits per component plus 8
unused bits for alignment), that will result in completely wrong colors or,
with my patches, an explicit error.
