get-startvmpolicy causes a 'systemDefault' was not found error

I was recently trying to set start orders for Trend Deep Security AV appliances on my hosts as I found some were not configured correctly.  Upon running the get-startvmpolicy command across the VM's to check their status, on some of them I received the following error:

Get-VMStartPolicy : 4/06/2015 9:53:22 a.m.    Get-VMStartPolicy        Requested value 'systemDefault' was not found.At line:1 char:40+ foreach ($vm in $vms){get-vmstartpolicy <<<<  -vm VM}    + CategoryInfo          : NotSpecified: (:) [Get-VMStartPolicy], VimException    + FullyQualifiedErrorId : Core_BaseCmdlet_UnknownError,VMware.VimAutomation.ViCore.Cmdlets.Commands.Host.GetVMStartPolicy

So it turns out after logging this with VMware that it is a known bug and has the Bug ID 1336800.  This is set to be fixed in the next release of PowerCLI
