Hello,

This is my first real bug report so please advise how i could provide more useful information.

I am not certain if the severity is correct.

The bug: segfault when creating a spline with a dashed linetype or opening a file containing one.

The bug isn't present with the dwg extension installed

Steps to reproduce:
1. create drawing
2. create spline
3. set linetype to dashed
4. crash
