Error when running unreal:display

[sygi]

Hello,
when I was running your code, I got an error for the display target:

Fatal Python error: (pygame parachute) Segmentation Fault
Assertion 'pa_atomic_load(&(b)->_ref) > 0' failed at pulsecore/memblock.c:597, function pa_memblock_unref(). Aborting.

It seems it happens when resetting the environment, namely when checking the argument of the if, namely in Com_init (it seems gc->command_line is empty -- do you know if it should be so?). It looks like a problem within the lab, but on the other hand I have run the tests of the lab itself and they passed (including showing some video of the random agent).

Do you have any idea what could be wrong and how to debug it?
Thanks for the help and for providing the library :)
