System Information
OS: Ubuntu 13.10
Linux kernel: 3.11.0-19-generic

Graphics:
VGA compatible controller: Intel Corporation 4th Gen Core Processor Integrated Graphics Controller (rev 06)
3D controller: NVIDIA Corporation GK107M [GeForce GT 750M] (rev a1)

Blender Version
Broken: blender-2.70-b179647-linux-glibc211-x86_64

Short description of error

Using the AAC audio encoding and setting the audio bitrate to 320 causes Blender to freeze (on frame 6 for me). Setting bitrate to 318 or to 340 got rid of the problem.

Exact steps for others to reproduce the error

Open new Blender file and go to the VSE
SHIFT+A -> Sound and pick a sound clip
In Output panel of Render context, set File Format to H.264
Under the Encoding panel, select AAC for Audio Codec
Set Audio bitrate to 320
Hit Animation and it should freeze
