StackOverflowException with Update Manager PowerCLI and WMF v3

While doing some patchmanagement I faced an issue with the current Windows Management Framework 3.0 (WMF) and the VMware vSphere Update Manager PowerCLI 5.1. Everytime when i invoked one of the VMware.VumAutomation cmdlets the PowerShell crashed with an StackOverflowException:
