first up .... should there be a spare ',' after the skeleton name? That would indicate there is a secondary skeleton to use which you haven't defined.

You also have the 'type' listed as 'barb infantry gaul' . If you have copied and pasted from another model, you may not have changed this. You would then have 2 units with the same 'type'. All the others you have changed to barb_infantry_gaul3 .

Now...what you don't mention, is whether you are running -show_err and if it is showing a message when it crashes. This will tell you what it is unhappy about.

Some errors, though, don't give you a message. Would help to know a bit more about the error
