Media server crashes at boot

On hrev34609, media_server is quite reliably crashing at boot with the following backtrace:

However, if I terminate it and then start it via the media preflet, it comes up just fine.

In case it matters, the only active hardware I have for the media server is an SBLive 5.1 powered via the emuxki driver.
