gdb captured backtrace of segmentation fault

So it turns out I am able to stream successfully from di.fm, I think I may have
just needed to sign up(!) :-)

Regardless though, launching of the web player does seem to be a bit spotty.
Though I'm not sure if it caused by this bug or something else...

I was able to get the attached backtrace by attaching to the browser's
flashplugin subprocess! Hopefully it does help. To reproduce, all that seems
necessary is to visit di.fm.
