Hello Development,

  here's  a  backtrace.  i'm  running  cvs  as of yesterday, before the two last
commits  from  isaac.  it  segfaults when a recording finishes it seems, when it
starts the logodetection.. (and NO, those shows where only recorded fo r testing
purposes,  i don't watch those ;) (those who got fucked yesterday, my girlfriend
watches tho.. she was pissed.. ah well :/ )backtrace:
