[Mono-dev] Data protection failed exception

[Neale Ferguson]

Does this problem description ring any bells before I go too much further
problem shooting (done a couple of hours already, so should have sent this
first!):

1. Application Version: Mono 4.3
2. redhat 5.1-5.3
3. intel x86
4. Priority: 20 
5. Description: Data protection failed.::::: at
System.Security.Cryptography.ProtectedData.Protect

Details of our issue:
When trying to do an Process.Start() to start a process I will get this
error:

This doesn't happen all the time and is random and it always works as root
but as a standard user I would get this error. Is there any way to turn
off whatever security check this is trying to do since we really don't
care?
