snicker: I'm sorry it's been so long since you've gotten a response.
Are you still getting these crashes? If so, it would be good if you could run
gpa under gdb. Then, when it crashes, you should be able to get a backtrace
using: 'bt full'

Unfortunately, I don't use Windows so I can't provide more exact instructions.
I hope Andre will correct any details I've gotten wrong.
