On my system track-o-bot crashes with an error about mit-magic-cookie-1. I decided to debug and find the problem and I found it - on my computer echo $DISPLAY returns :1, and this function call returns NULL meaning that it could not open a display with name :0.0 - see xlib-docs. Therefore the Display variable is NULL and is passed in some other function and that causes SIGSEGV.
