NoMethodError undefined method [] in post/windows/gather/enum_patches

[bcoles]

Cross-posted from rapid7/metasploit-payloads#242:

I'm currently trying to escalate privileges on a Windows machine. Whenver I try to enumerate over all installed patches to find a missing one I get this from the meterpreter:

meterpreter > run post/windows/gather/enum_patches 

[-] Post failed: NoMethodError undefined method `[]' for nil:NilClass
[-] Call stack:
[-]   /usr/share/metasploit-framework/modules/post/windows/gather/enum_patches.rb:70:in `run'

Meterpreter used:

* `exploit/windows/meterpreter/reverse_tcp`

No idea if this is a valid issue. I wasn't able to reproduce it on Win 7 (x64) as low priv user.
