Thank you for the patch. Unfortunately, this bug probably does not meet the standard for a update to the "stable" release. The guidelines [0] are that a bug to be fixed in stable should have at least severity "important", which is defined as
a bug which has a major effect on the usability of a package, without
rendering it completely unusable to everyone.
which I think this probably doesn't justify.
