What should the severity for this bug report be?

       0) Feature request, or maybe a bug which is very difficult to
       fix due to major design considerations.

       1) The package fails to perform correctly in some conditions,
       or on some systems, or fails to comply with current policy
       documents. Most bugs are in this category.

       2) This bug makes this version of the package unsuitable for
       a stable release.

       3) Dangerous bug. Makes the package in question unusable by
       anyone or mostly so, or causes data loss, or introduces a
       security hole allowing access to the accounts of users who
       use the package.

       4) Critical bug. Makes unrelated software on the system (or
       the whole system) break, or causes serious data loss, or
       introduces a security hole on systems where you install the
       package.
