Thomas (or anyone else), could you please try brasero on your squeeze box (I 
currently don't have any burners at reach), at least the bug claims brasero 
version: 2.30.3-2. Reporters also claim: "I think it only fails if you select 
the option to burn a data project directly from disk. Burning
iso images works."

Then try to apply the patch at:
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=617409#44
(this is against brasero-3.4.1, but the change is easy to adapt) and re-run.

I have the impression that the exit status of growisofs child is incorretly 
inspected via WEXITSTATUS (status), half way the burning task completes and 
way before growisofs actually returns success. I think growisofs is signalled 
(could be SIGPIPE or something more brutal)

I also forgot to inspect waitpid() returning -1, but I don't actually think 
this is the case since this would return true anyway.

I'm not at all convinced that libisofs itself is to blame. Brasero libisofs, 
and growisofs plugins is another matter.
