btrfs-progs-3.14.1 has been pushed to Fedora 19 and 20 for testing.

I frankly have no idea if this will resolve your bug or not, but if you test it and find that it does, please take the opportunity to close this bug.  :)

Thanks,
-Eric
Comment 13 Bjoern Engels 2014-05-14 16:42:41 UTC 
I'd expect some notice on a non-btrfs-filesystem but the crash is fixed. :-)

# btrfs device stats /dev/sda2
ERROR: getting dev info for devstats failed: Input/output error

Thanks,
Bjoern
Comment 14 Eric Sandeen 2014-05-14 16:44:31 UTC 
That's what I found too.  Thanks for verifying.

Agreed that it's not the friendliest error...
