I can confirm this. I also bisected and it is caused by

This can be the same problem with the "P" key ? link: https://developer.blender.org/T41391
No. First of all the bug in the link couldn't be reproduced on systems including a video card. Secondly, the bug ascribed here doesn't involve a crash. Thirdly, hitting the P key hasn't anything to do with it. The attached blend shows a mesh being deformed by an armature. Press P to see how this doesn't work in the BGE.

Hmm... This probably shouldn't be called: 'Armature Modifier broken' because Mesh deformation does work! Only you have to activate the action. I'm closing this. If someone has an objection to this, please do reopen it, but just keep in mind the bug shown in the blend is more of a Viewport type of thing.

The problem from the original file "Armature_Modifier_bug.blend" is still not solved! Deformation works only while action is applyed and not when you manualy change the position of bones. If you manualy pose your character, or change the positions of bones via python script, in BGE will be the character in rest pose without any deformation (same as parented object without armature modifier).
