mp4box segmentation fault with -split

[Jon-o Addleman]

MP4Box is crashing with a segfault when I try to split an m4a into several pieces. The m4a came from a youtube video that I downloaded (with youtube-dl) and converted to m4a with 'avconv -i file.mp4 -acodec copy -vcoded null file.m4a'.

Then when I try 'MP4Box -split 2700 file.m4a' (to split into 45 minute chunks) I just get a segmentation fault. (longer or shorter lengths don't seem to affect it at all).

This is with an up-to-date ubuntu 12.10, gpac 0.5.0~dfsg0-1.
