severity 820105 wishlist thanks I don't know if the reason for suggesting "grave" severity here was to make it an RC bug, but otherwise grave means:
"makes the package in question unusable or mostly so, or causes data loss, or introduces a security hole allowing access to the accounts of users who use the package." which definitely doesn't apply at all. Actually looking at the technical criteria, there is no "violation", "usability" or "usefulness" issues. Setting severity accordingly.
