Hah, thanks for giving me a reason to hunt this one down.
The Forsaken testers have been after me a while to fix it...
anyways... here you go. A fix.

Step 1: In PlayerState.h around line 34 change:
	QAngle v_angle;
		To
	CNetworkQAngle(v_angle);

Step 2: In player.cpp around line 6484 add in after sending the dead flag:
	SendPropQAngles (SENDINFO(v_angle), 13),

Step 3: In c_baseplayer.cpp around line 85 add in after receiving the dead flag:
	RecvPropQAngles (RECVINFO(v_angle)),

Step 4: You must make all calls to v_angle safe. In baseplayer_shared.cpp around line 211 add in:
	if (!pMoveParent)
	{
		return pl.v_angle.Get();
	}

	Around line 216 change AngleMatrix to use pl.v_angle.Get().
	Around line 227 change the return value of LocalEyeAngles to pl.v_angle.Get().

Step 5: In prediction.cpp around line 1700 in GetLocalViewAngles change the else portion to:
	else
	{
		ang = player->pl.v_angle.Get();
	}

Step 6: In c_baseplayer.cpp around line 437 in the function SetLocalViewAngles change that to:
	pl.v_angle.GetForModify() = viewAngles;

Step 7: In player.cpp around line 598 in SnapEyeAngles change pl.v_angle = viewAngles; to pl.v_angle.GetForModify() = viewAngles;
	Around line 2914 in the function PhysicsSimulate change VectorCopy ( pl.v_angle, ctx->cmds[ i ].viewangles ); to VectorCopy ( pl.v_angle.GetForModify(), ctx->cmds[ i ].viewangles );
	Around line 3052 in PlayerRunCommand change VectorCopy ( ucmd->viewangles, pl.v_angle ); to VectorCopy ( ucmd->viewangles, (QAngle)pl.v_angle.Get() );
	Around line 3056 in the same function change VectorCopy ( pl.v_angle, ucmd->viewangles ); to VectorCopy ( pl.v_angle.GetForModify(), ucmd->viewangles );
	Around line 4427 in the function Restore change QAngle newViewAngles = pl.v_angle; to QAngle newViewAngles = pl.v_angle.Get();

Step 8: In player_command.cpp around line 177 in SetupMove change move->m_vecAngles = player->pl.v_angle; to move->m_vecAngles = player->pl.v_angle.Get();
	Around line 362 in RunCommand change g_pMoveData->m_vecOldAngles = player->pl.v_angle; to g_pMoveData->m_vecOldAngles = player->pl.v_angle.Get();
	Around line 367 in RunCommand change player->pl.v_angle = ucmd->viewangles; to player->pl.v_angle.GetForModify() = ucmd->viewangles;
	Around line 371 in RunCommand change player->pl.v_angle = ucmd->viewangles + player->pl.anglechange; to player->pl.v_angle.GetForModify() = ucmd->viewangles + player->pl.anglechange;



Enjoy!

P.S. The cause of this is in baseplayer_shared when calling EyeAngles.
It returns pl.v_angle which is initialized to a zero-vector.
By enabling it to be sent over the network this resolves the issue.
