Use of uninitialized value in string eq at /usr/bin/vmware-cmd line 392 error?

I am getting the following error with vMA 4.0 build 161993:

[vc-01]$ vmware-cmd -T esx-08 /vmfs/volumes/4a4d5344-49ca8461-cc25-003048d27c87/SAM/SAM.vmx getstate

Use of uninitialized value in string eq at /usr/bin/vmware-cmd line 392.

Use of uninitialized value in string eq at /usr/bin/vmware-cmd line 392.

getstate() = on

[vc-01]$

Wondering if anyone else is getting the same?

I am going to try and write some simple bash scripts to do monitoring of my infrastructure and vmware-cmd looks like a necessary part. I'd rather not have to parse around the errors!
