environment_info plugin not working correctly

Have a look at this submission:

https://certification.canonical.com/hardware/201101-6983/submission/CPbTHbeyBmxqU9O/results?batch=153

Wireless tests didn't run:

wireless/wireless_connection_open_bg certification Unsupported Job requirement not met: 'environment.routers == 'multiple''

debconf shows that the environment_info config variable is correctly set:

$ debconf-show checkbox

Also if I create a job with command echo $ROUTERS, it does output "multiple" (no quotes). So something else is fishy.
