Strange crashes when using media-element

I'm encoutering strange crashes when i showed my creation to some
colleagues at work. Actually, it crashed on every browser i tested...which
is strange because i've been working a lot on it the past days, and never
had a crash once. It appears to be a problem with the retrieval of the mp3
i imbedded in the media-element, which is strange because the
audio-tag-player seems to have buffered the whole thing. This is the error
i get:

Failed to load resource
http://petervandernoord.nl/patchwork_js/audio/flim.mp3

I have no idea what's going on (maybe the firewall here at work, maybe my
server is crap), but i get a complete crash of the browser (the 'aw snap!'
thing), which seems a bit too much for whatever it is that's happening.

I can reproduce it by doing this:
- go to petervandernoord.nl/patchwork_js/
- add a mediaelement and a destination + connect
- (i usually added a analyser to the mediaelement as well, but i doubt this
has anything to do with it)
- press play on the player in the bottom
- do nothing and wait for it to crash. might take a while, but it happened
here at work *every* time, on different computers and OS (the chrome i'm
running here now is 20.0.1132.57)

Any idea what happens here?

regards,
Peter
