Bug#996483: mp3blaster FTBFS: error: format not a string literal and no format arguments [-Werror=format-security]

Source: mp3blaster
Version: 1:3.2.6-2
Severity: serious
Tags: ftbfs

mp3blaster fails to build from source in unstable due to ncurses having
gained format string annotations. A non-parallel build now ends as
follows:
