Comment 1 for bug 50747

The package does not exist in Dapper and Edgy, but is in Feisty (where the problem has been fixed). As it is quite unlikely that a package will be introduced in an already-released version, I'm afraid I'll have to reject your bug. If you really think should be in Dapper/Edgy, you might want to request a backport, but I'm not sure what the policy in such cases is. Thanks for reporting this.
