[@ mozilla::MediaFormatReader::DecoderFactory::Wrapper::Init ] looks like another related signature.

Bughunter has seen this on a NSFW url. It appears to be Windows only null pointer reference. Opt reproduces this signature. Debug gives

Though I can't reproduce with the original urls in comment 0 and comment 1 with a local build.

There's nothing related in any of the push there.

Marking duplicate of 1400537 as the first report is on a previous build ID, they are the same crash, just one on opt build and the other on debug
