Any correlations here? We'll remove this code path once we're using our own MP4 demuxer, but that'll be a few months away. Unless this is happening on MP3 files, we may need to keep using the WMF backend for them.

This is my crash report: https://crash-stats.mozilla.com/report/index/827bef5e-f869-4428-b410-aea2c2130724 I'm almost sure I didn't have any page using MP3/MP4 or anything like that. Only Gmail and Facebook (only text and images, no video)

Hi Guilherme, do you have any codec packs or media players other than Windows Media Player installed? Based on the crash report it looks like there's a bad media decoder trying to read an audio stream.

I have VLC media player (and its plugin VLC Web Plugin 2.0.6). No codec pack.

We've not uesd the WMFReader for years.
