mythexport deletes file after encoding

I send a userjob to mythexport and after about 60 seconds the job was startet. I can see the process working and the output-file in the export-directory growing. But after mythexport has finished the output-file is gone. I've testet the ffmpeg command before adding it to mythexport and it worked fine. (It looks like there is something wrong with AtomicParsley?!?)
