[Buildbot-devel] "TypeError: 'NoneType' object is unsubscriptable" when viewing slaves

[Jason Edgecombe]

Hi everyone,

When viewing build slaves, I'm getting a TypeError.

The example URL is:http://127.0.0.1:8010/buildslaves/centos6-x86_64

Here is the error text:
---------------------------------------------
*web.Server Traceback (most recent call last):*
exceptions.TypeError: 'NoneType' object is unsubscriptable

118 |       except ValueError:|
exceptions.TypeError: 'NoneType' object is unsubscriptable
---------------------------------------------

I'm getting this error in my test environment and production. My 
production config, without the centos6 buildslave, is at:
https://github.com/edgester/afsbotcfg/blob/master/master.cfg

I appreciate any help that you can provide. 'buildbot checkconfig ..' 
says that my config file is good.

Thanks,
Jason
