[bug] tab crash on media playback

[Christian König]

Hi Cory,

I'm the author of the patch you bisected, but that looks like a bit 
strange bisect result.

The patch in question shouldn't have an functional change, it just 
restructures the code.

Can I send you a debugging patch which prints a few lines into dmesg 
when problems happen?

Thanks in advance,
Christian.
