The labels and descriptions are used in places like the recent changes page and article history, and such lengthy stuff can make stuff time out when trying to view it on the wiki.
Version: master
Severity: major

The terms table are limited anyhow, but I'm not sure if we should copy this value as the terms table is used mainly for lookup. We could warn the user if the length goes above this value, like the warnings while someone is uploading an image.
