avconv segfaults with aac / m4a

[Alin Andrei]

avconv segfaults with aac / m4a files. So is VLC.

Here's the output of avconv trying to merge an mp4 and a m4a file:

avconv -v debug -i 'Hottest New Jam-aoJS_g6mYj8.f137.mp4' -i 'Hottest New Jam-aoJS_g6mYj8.f140.m4a' -c copy 'Hottest New Jam-aoJS_g6mYj8.mp4'
