dvdauthor 0.7.0 - segment fault

hello,
 i'm running RH (scientific Linux 6.2) clone with all security applied.
dvdauthor has been running for years without any issues.
But a few days ago it started crashing. I didn't make any changes to the
script that calls it. Please advise


 dvdauthor -v
DVDAuthor::dvdauthor, version 0.7.0.
