This patch was removed as it shouldn't have been included in the first place. Upstream had never applied those commits to the 0.5.x branch, and the issue couldn't be reproduced.
I have personally tried the example multimedia file that demonstrated the original issue on the ffmpeg 0.5.x branch, and could not reproduce the issue either, therefore this patch was unnecessary, didn't affect security, and simply introduced the regression.
