I have a few Matroska files containing H.264 video and AAC audio which cause
severe hiccups and finally an abort, with the following message:

ERROR               ffmpeg :0:: Internal error, picture buffer overflow

Backtrace from the abort is:

I have put the beginning of one such file (8MB) on my webserver at:

http://www.tdb.fi/~tdb/GH13.mkv

It's the beginning of Ghost Hound episode 13, as fansubbed by Shinsen-Subs. 
Please think before downloading, I only have 1Mbit upstream and I hope to not
get it bogged.  The crash can be obtained with:

gst-launch-0.10 filesrc location=GH13.mkv ! matroskademux ! ffdec_h264 !
appsink sync=false

The sync=false is optional, but makes it reach the crash point much faster (6
seconds vs. a minute).
