The attached project has been used to generate both profiling data from a windows build and an X360 build.
The Dumps from PC and X360 are in the Dumps folder.
Right click the dump files and select Load In Profiler. This works for the PC but not X360. Some dumps made on the X360 "works" but only imports 1 frame and other dumps make the Editor crash.

Repro:
Right Click the 'x360_profile_dump'
Select 'Load In Profiler'
Observe Crash
