How would you rate the severity of this problem or report?

1 critical 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.
2 grave makes the package in question unusable by most or all
users, or causes data loss, or introduces a security hole allowing
access to the
accounts of users who use the package.
3 serious is a severe violation of Debian policy (that is, the
problem is a violation of a 'must' or 'required' directive); may or may
not affect
the usability of the package. Note that non-severe
policy violations may be 'normal,' 'minor,' or 'wishlist' bugs. (Package
maintainers
may also designate other bugs as 'serious' and thus
release-critical; however, end users should not do so.)
4 important a bug which has a major effect on the usability of a
package, without rendering it completely unusable to everyone.
5 does-not-build a bug that stops the package from being built from
source. (This is a 'virtual severity'.)
6 normal a bug that does not undermine the usability of the
whole package; for example, a problem with a particular option or menu
item.
7 minor things like spelling mistakes and other minor cosmetic
errors that do not affect the core functionality of the package.
8 wishlist suggestions and requests for new features.

Please select a severity level: [normal] 4
