Reproduced: reading and encoding an audio disc
track 14 and track 16 missing after the disk is processed.

using public CDDB from gnudb.org
DISCID=f8121b12

Diagnostics:
Watching the directory while the disk is processed,
the following wav-files are created and deleted:

16_Mass_in_B_minor_for_soloists_chorus__orchestra_BWV_232_BC_E1_Osanna_Benedictus_Agnus_Dei_et_Dona_nobis_pacem_Osanna_in_ex
14_Mass_in_B_minor_for_soloists_chorus__orchestra_BWV_232_BC_E1_Osanna_Benedictus_Agnus_Dei_et_Dona_nobis_pacem_Osanna_in_ex

Note the missing exensions.

Suggested fix:
grip should truncate the name with room for the needed extension.
