System Information
Windows 10 64, Nvidia GT 425M

Blender Version
Broken: 2.77a abf6f08

Short description of error
Standalone player crashes after using the load file function more than 32 times in the same session.

Exact steps for others to reproduce the error

unzip the zip file
open 1 of the blend files
start the standalone player
press the 'W' key 33 times

Standalone player crashes consistently loading the 33rd time.

Notes:

tested using the logic brick actuator 'game' and a python script with 'bge.logic.startGame('//filename.blend')' having the same result
embedded player doesn't crash.

Aparrently the euler_Type has an issue. I looked for specials operations made for mathutils types but i found nothing, maybe someone know better that than me.
