Error calling vm.is_powered_on() "AttributeError: 'DynamicData_Holder' object has no attribute '_propSet'"

[GoogleCodeExporter]

What steps will reproduce the problem?
(intermittent issue)
1. Create a linked clone
2. Disconnect VIServer session
3. Use linked clone for a while
4. Reconnect VIServer session to VCenter host
5. Call linked_clone_vm.is_powered_on()

What is the expected output? What do you see instead?
Expect to get "powered on" state. Instead, I get an exception.


What version of the product are you using? On what operating system?
pysphere-0.1.8-py2.7 on Ubuntu 12.04

Please provide any additional information below.

Here's the stack trace:

I'm happy to collect further diags if you would find it useful. Any suggestions 
for a workaround?

Cheers.

I have the same issue when I was trying to get the computer resource properties for the host.
Sample code:

> for cr in cr_mors:
>         if cr_mor:
>             break
>         for p in cr.PropSet:
>
