Grafana: [Bug] Templating OpenTSDB

[Minims]

Hello,

• Gafana 4.0.2 & Gafana 4.1 beta
• DataSource OpenTSDB (All versions has the problem)
• Linux Debian Jessie.

TEMPLATING

$os: tag_values(load.gauge, os)
os can be debian and others
$host : tag_values(load.gauge, host, os=$os)

ERROR

Template variables could not be initialized: can't parse query param 'm=load.gauge{host=*,os=d,os=e,os=b,os=i,os=a,os=n}'

EXPECTED

if $os is 'debian' , the string has not to be split in chars
'm=load.gauge{host=*,os=debian}'
