Package: gs-aladdin
Version: 5.50-8
gs crashes when used with vncserver: there seemed to be too few colors
for a colorcube and its switched to grayscale (somewhere in
gdevxini.c) , but the color lookup function still tried to use a color
cube. This patch does it for me (maybe someone forward it to an
upstream maintainer? i'm not in any gs mailinglist -- thank you :)
