Thanks for reporting the error. I have been able to reproduce it, as follows: 
Step 1. Start Tonatiuh 1.1.1
Step 2. Load the demo file: SolarFurnace_normal.thn
Step 3. Click on "Sun Light>Define Sun Light..."
Step 4. Change "Sunshape Type" from "Pillbox_Sunshape" to "Buie_Sunshape"
Step 5. Click the OK button of the "Define Sun Light" dialog
After Step 5 in most cases the program crash, but not always. This may be a 
simptom of a bad memory allocation. We will look into the problem and try to 
solve it as soon as possible.

FWIW I just saw this segfaul with 1.1.3 on Ubuntu 10.04 LTS. Here is GDB output 
showing the source of the problem, possibly:
