VLC crashes EVERY time on RTMP h264 stream

[Markus Kienast]

Resubmission of Bug #1304041 with additional stack-trace from "apport-bug vlc". Hope this is done right now.

This happens reliably all the time I try to open an RTMP h264 stream. In saucy, this was stable!!!

Here the stream I am using, coming from a Wowza server: rtmp://paris4.sfe.tv/sfe-hd/sfe-hd.stream

This stream works well in saucy and also on trusty totem.

I have problems with all h264 videos. It starts playing fine, but when scrolling to different positions along the timeline it crashes the "Videos" app and VLC alike.
