These are from content process stuck creating a decoder. The vast majority of the reports don't have the IPCShutdownState annotation set which means they didn't respond to the content shutdown message at all for five seconds and didn't even begin to shut down.

There's lots of inlining going on but I believe that the call we're stuck in is this one.
