createScriptProcessor crashing chrome canary?

Doing a createScriptProcessor call seems to completely crash my canary,
while the regular chrome version does what it's supposed to do. i'm not
doing anything fancy, this...

context.createScriptProcessor(2048, 0, 1);

... is enough to give me the sad-face thingie. No error messages, nothing.
Does anyone have an idea what's going on?
