Unreal Engine Issues and Bug Tracker (UE-20199)

Description

Submitted by a licensee on UDN. I verified it and have attached the test level that he provided.

In the test map. some boxes fall and break. Walking straight into the boxes causes the editor to crash.

Steps to Reproduce

1. Open attached project
2. Play the level
3. Destructible boxes fall in front of you
4. Push W key to walk straight into the boxes
*Crashed every time I tried it, but licensee said once in a while it doesn't, so might take more than one try

Callstack

Fatal error!
