q3Scene.Step is freezing

[1-max-1]

dump_7.txt

I have a scene with 13 bodies. 12 of them are different types of walls and 1 is the dynamic player body. You can shoot projectiles which are also dynamic bodies. Everything usually works fine except for when I shoot right into the space where 2 walls touch. The whole app just stops and freezes, windows shows the whole 'not responding thing' but it doesn't crash, almost as if it were going into an infinite while loop. I set some breakpoints to see what was happening - still don't really see the problem but execution goes into q3Scene.Step() and never comes out. I assume there's a problem in there somewhere, or maybe I didn't set up my bodies correctly. I've attached a dump of the scene just before the freeze. Any help would be greatly appreciated - I've been struggling with this for hours and I'm not a physics engine person so it's pretty hard to wrap my head around this. Thanks.
