Hello,

I'm testing your ice plugin and I run into a segmentation fault:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x163d3f6]

I'm getting a similar error for the kubernetes-dasboard ns as well, but it works with kube-system, default.

My environment:
