Known issue, yes. Disable caching (or remove your config for it) as it's currently broken.

Leaving open, since we don't have a tracking issue for this yet.

Opened #1761 to disable caching altogether regardless of user setting, since looping is worse than a slow analysis (until we fix it).

Pushed to daily and beta, so the looping should go away for everyone on those channels. Stable never had this bug, so is safe (but we'll be upgrading stable soon anyhow, regardless of the status of caching, since stable never had it enabled by default).
