Get rid of SafariAdBlock and any other InputManagers you've thrown on your system. If you need help finding them, run this:
Are you reading any http net-radio or video streams using iTunes?
The _ZN14HTTPReadStream11streamEventEm function appears in the callstack shortly after __CFRunLoopDoSources0 is called. The latter probably examines the status of known streaming sources and subsequently calls the former upon noticing that there is indeed something worth streaming.
I can only assume that there are invalid data inside the stream which the streaming code doesn't handle properly, leading to an absurd memory allocation instead of ignoring the faulty data.
Try to notice which audio/video sources you are playing from when this bug appears. If you can pinpoint one that systematically causes it, you should then include its URL in your next Apple Crash Report.
Note that this crash implies up to two bugs in iTunes' code:
(and I'm pretty naive to reply to a one year old question, but well, you never know :) )
