Bug#788708: iceweasel: GStreamer causes segmentation fault

[Fabio Natali]

Package: iceweasel
Version: 40.0.3-3
Followup-For: Bug #788708

Hi everyone!

Since a recent upgrade, Iceweasel has been crashing regularly whenever
a video is loaded (eg on youtube pages). The crash happens immediately
and no part of the video is shown.

I'm on Sid but tried different Iceweasel versions (testing, unstable
and experimental). All of them were affected by the issue.

I tried with an empty `.mozilla` folder and with the `-safe-mode`
option - still no luck.

Any hints?

Thanks,

Fabio.
