Segfault in cueconvert, apparently from 'LANGUAGE_MAP' tag

I tried to use cueconvert to convert a .toc file
generated by cdrdao to a .cue file to embed in a .flac
file, but got the following error:

CD_TEXT: unrecognized line
0:
Segmentation fault

I've attached a .toc file that displays this problem,
and I've managed to reproduce it on another .toc file
that has the same LANGUAGE_MAP part (which seems to be
what's causing the problem).

I generated the toc file using:

cdrdao read-toc --device ATAPI:0,0,0 --driver
generic-mmc-raw --datafile audioslave-audioslave.wav
--with-cddb audioslave-audioslave.toc

(Leaving off the --with-cddb works, but then I don't
get any titles, which makes the exercise rather
pointless for me...)

I'll take a look myself and add a note if I find a
solution, but as a non-programmer that probably won't
be very likely. :-)
