LS 3.3 + L2TP VPN + AFP Mount = Hard Crash

I am experiencing a painful issue that is preventing my remote working. When I VPN (L2TP) with the native OSX client (Mavericks 10.9.2) and then mount a remote drive using AFP and finder, I have a hard crash. Thus, I cannot access my files remotely. Disabling filtering does not fix the problem, nor does explicitly allowing the OSX Kernel.

Does anyone else have this issue or have a workaround/fix?

Thanks in advance!
