It appears this exact same crash got reported again in this thread. The second report has a few more details (and an unmangled stack trace, thanks!):
Added detail:
NO UNUSUAL BEHAVIOR OTHER THAN COVER ART BEING REPLACED
WUTH GRAYED BOX WUTH PODCAST NAME
AFTER DEVICE IS AWAENED AFTER USING
SLEEP TIMER
FIR PLAYBACK.
The above answers some of my questions in my previous comment, but it would still be interesting to confirm whether this has been seen also with 3.4.0?
