Timeout errors for +subscriptions

Trying to load https://launchpad.net/~ubuntu-server/+subscriptions generates an oops:

OOPS-e57099dcc7fcc8b77fe861a871deb323

Same thing trying to access it as a logged in user in from the LP API:

Logging in to Launchpad...

Running this with launchpadlib.launchpad.Launchpad.login_anonymously() works fine.

I've also noticed the oops triggers for certain users:

      https://launchpad.net/~ubuntu-server/+subscriptions
      https://launchpad.net/~paelzer/+subscriptions
      https://launchpad.net/~bryce/+subscriptions
      https://launchpad.net/~racb/+subscriptions

but no oops when running it for these users:

      https://launchpad.net/~canonical-server/+subscriptions
      https://launchpad.net/~jchittum/+subscriptions
      https://launchpad.net/~slyon/+subscriptions
      https://launchpad.net/~lvoytek/+subscriptions
