Indexing issue with grafana package in Helm remote repo pointing to https://storage.googleapis.com/kubernetes-charts

Steps to reproduce:
-Create helm remote repo pointing to https://storage.googleapis.com/kubernetes-charts
-Try resolving grafana-0.6.tgz
-See the following error:
2018-02-14 09:55:39,874 [art-exec-18] [INFO ] (o.a.a.h.HelmServiceImpl:203) - Starting Helm index calculation for helm-google-remote-cache
2018-02-14 09:55:39,875 [http-nio-8081-exec-5] [INFO ] (o.a.r.HttpRepo      :427) - helm-google-remote downloaded  https://storage.googleapis.com/kubernetes-charts/grafana-0.6.tgz 8.38 KB at 1,066.85 KB/sec
2018-02-14 09:55:39,903 [art-exec-18] [ERROR] (o.j.r.h.HelmMetadataIndexer:92) - Error occurred while indexing: null

This seems to be due to the version of grafana (0.6, instead of 0.6.0) of the index.yaml (https://storage.googleapis.com/kubernetes-charts/index.yaml):
