Bug 267196

Version:           2.0.3
OS:                Linux

Using the change data file leads to a crash

Reproducible: Always

Steps to Reproduce:
- Load CStk vs INDEX from the TWIN1xxx.txt file in src/sample_data
- Call the change data file tool, select all vectors from TWIN1
- Select the duplicate option, including dependents
- Click OK or Apply => crash

Actual Results:  
It crashes

Expected Results:  
It duplicates the vectors and curves, as it used to not so long ago...

It seems to be an off-by-one index. dup_output_prims has only 12 items while output_prims has 13...

Here is the backtrace:
