serializer and facewinding - crash on showdebuglines

i noticed what if i create and export my terrain collisions with FW_REVERSE, then let it import and press F3 to show debug lines, the app just crashes without any error. in debug mode, it breaks, but can't show the code position and asks me if i want to see the disassembly.
it works fine with FW_DEFAULT, and plsm2 collision works fine if i create it with FW_DEFAULT now (latest CVS version)

hmmm.... that's odd... I'll have to try and take a look into that when I have some time.

if anyone else can help narrow down the problem I'd appreciate it!
