Textures/Sky/broken.rgba seems to be literally just that, broken. Or rather, corrupted. As do scattered, few, and cirrus. fg/osg (but not plib) frequently crashes and I've traced it down to the cloud cover (clouds == likely crash, or crazy sky as in http://hans.fugal.net/tmp/fg/fgfs-screen-007.png, no clouds == probably no crash).
ImageMagick does not think these corrupted (identify(1) should return nonzero if it encounters a corrupted file), but some of them are obviously not being interpreted correctly by ImageMagick. Try "display cirrus.rgba" to see what I mean. Unfortunately this means we can't just use convert(1) or mogrify(1) to fix the files that are broken. On the other hand opening them in Gimp they all look as they should. I saved them as PNG and then ran "convert $i.png sgi:$i.rgba", and the crashes went away. Melchior says that gimp sometimes creates corrupt SGI files, and this is the likely root of the problem. I haven't been able to figure out a way to systematically identify corrupt SGI files (no doubt there are some more out there), but I'm moderately confident that this takes care of the Sky textures. Please import the fixed textures into CVS from http://hans.fugal.net/tmp/fg/Sky , or someone close to textures might prefer to fix them himself.
