Comment 3 for bug 1548813

Just confirming the root cause from IRC:

<dimitern> voidspace, bootstrap error is due to spaces discovery indeed: "GET /MAAS/api/1.0/spaces/?op=list HTTP/1.1" 400 276 "-" "Go-http-client/1.1"
<dimitern> here's the line causing it https://github.com/juju/juju/compare/maas-spaces2#diff-9f2d224cfe3d5b5450772b51d95b625aR67

Should be 'read', not 'list'.
