No crash for me either on git or 0.5.1 running on Ubuntu Gutsy amd64

On the first try I got a hard reset.
Since then it plays perfectly fine in the background. So I'm blaming the hard reset on something else and close this. (x86 btw)

So unless someone gives me a backtrace, I'm gonna think this one is fixed.

With current git (post 0.5.3)

hrm, that file plays fine here (since 5 minutes). Out of interest, what video/audio combinations do you have enabled (ffmpeg/mad/gstreamer)?

I use gst only
I disable mad & ffmpeg explicitly at start-up

This should be fixed with git f31f005192c5b59e3fa793fef78cc8f06a30ba1b

Confirming it is fixed
