nuvexport-xvid fails with segmentation fault (maybe related to mythtranscode)

[anonymous]

When using nuvexport-xvid (or any other exporting method) mythtranscode fails with a segmentation fault. I'm running SVN revision 13553. I don't know exactly how I should debug this, but this is the output on the console:

  1. DOK: Notfallstation Everest:
     Die höchstgelegene Klinik der Welt (Mon May 14 11:00 PM) 480x480 MPEG2 (4:3)
     Ob Hirnödem, Erfrierungen oder Khumbu-Husten, die NotÀrzte im Everest-
     Basislager sind fÌr alles gewappnet. In ihrer Klinik, der höchstgelegenen
     der Welt, behandeln sie vom betuchten Bergsteiger ÃŒber die Sherpas bis zu
     mausarmen Einheimischen jeden, der ihre Hilfe braucht. Unter schwierigsten
     Bedingungen bergen sie Verunfallte und haben schon manchem das Leben
     gerettet. Das bestÀtigen auch die Schweizer Bergsteiger Kari Kobler und
     Mario Julen, die bei den Dreharbeiten am Everest dabei waren.

I hacked export/ffmpeg.pm to use --debug and remove 2>&1, now I get the following:

Why hack? Please read the instructions at http://www.mythtv.org/wiki/index.php/Nuvexport#Debug_Mode

If mythtranscode is dying, it's a problem with mythtranscode, not nuvexport, so you need to run mythtranscode by itself, outside of nuvexport.
