Having trouble verifying Google Services for SharePoint installation

-- filed on behalf of a customer
The error shown seems to be coming from GssAcl.asmx. 

If it works on site collection on the same server and not the other, then 
something is going wrong here. The error is “ Server was unable to process 
request. ---> Object reference not set to an instance of an object.”. I am 
able to reproduce this with SoapUI, by running CheckConnectivity. I have had a 
look at the code to try to work out the issue. I have identified the line of 
code that is throwing the error, however, I do not know what is causing the 
error to occur.
The line of code is in GssAcl.asmx, Line 711:
SPUserCollection admins = web.SiteAdministrators;
If I comment out that line, then the "Verify installation" works.
