I attempted to get a backtrace, but I'm not sure it worked. After attaching gdb to the frozen polytopes process, gdb froze (ctrl-c did not work) until I killed the polytopes process from another terminal window. At that point gdb gave some error messages. It did then allow me to dump a backtrace, but I'm not sure it is a backtrace of polytopes. There are no debug symbols, even though I installed the package xscreensaver-gl-dbgsym=5.07-0ubuntu3. Attached is the dump of what I went through with some added comments. I hope this helps. If there's a better procedure to try, I will make another attempt.
