Thanks for reporting this bug and attaching a patch.

Since tahoe-lafs is in Universe in Ubuntu, it is community maintained, and not supported by the Ubuntu security team.

debdiffs that fix this issue for each Ubuntu release need to be attached to this bug, at which point the security team will publish the update.
