You seem to be trying to use antialiasing with a non-GL3 GPU. It is unfortunate that the client doesn't handle that more gracefully, but it seems you should have noticed that it started crashing when you turned antialiasing on, unless I'm missing something. Either way, the tip in the MagicMan's link should work:

That would turn antialiasing back off. Or you could just do so directly with the checkbox for it.
