Here is a way to reproduce it:
import ogg.vorbis
f = ogg.vorbis.VorbisFile("/usr/share/games/balazar3/sounds/oceane.ogg")
f.read(16384)
oceane.ogg is in balazar3-common package.
/usr/share/games/balazar3/sounds/oceane.ogg: Ogg data, Vorbis audio,
mono, 44100 Hz, ~96001 bps, created by: Xiph.Org libVorbis I (1.0.1)
This bugs breaks balazar3 and balazar-brothers.
Here is backtrace:
