Handling errors in HSI

[maris]

Hi there, i'm experimenting with HSI python interface and i'm trying to automate the panorama stitching process. One of my biggest fears now is debugging. 

For example, doing something in wrong order (editing image after it is added to panorama)

1) p = hsi.Panorama()

2) img = hsi.SrcPanoImage()

3) p.addImage(le_img)

4) img.setYaw(yaw)

in this example lines 3 and 4 should be swapped in order. However, the program just exits, without showing any errors. Is there any way to get some info from swig or c++ backend where / why the error was caused? Thanks
