Description

STR:
 1. In a debug build, visit http://vulturiceye.com/videos/maldek.webm
 2. Click around in the scrubber while the video is playing (beginning, end, middle -- mix it up).

ACTUAL RESULTS:
This appears in my terminal, for a good fraction of my seeks:
{
[Parent 28084] ###!!! ASSERTION: Wrong size for this Shmem!: 'Error', file /scratch/work/builds/mozilla-inbound/mozilla/ipc/glue/Shmem.cpp, line 459

###!!! [Parent][DispatchAsyncMessage] Error: (msgtype=0xFFFB,name=???) Payload error: message could not be deserialized


###!!! [Parent][DispatchAsyncMessage] Error: (msgtype=0xFFFA,name=???) Value error: message was deserialized, but contained an illegal value
