This is definitely a bug. Thanks for reporting.
I have made some fair-assumptions, and have sent out the
patch[1] to fix this bug (ref this email thread). Could you
kindly test it and report the result ?

[PATCH] Btrfs-progs: we need to have the string null terminated
Thanks, Anand

In working on a snapshot maintenance script I've noticed some odd
behaviour. Note the smbshare path. I've put this into its own subvolume
as I don't plan on snapshotting it.
In the first command's output, this path is printed correctly, however
in the second output it has "4.snap" appended, similar to the names of
the snapshots I made 22 hours ago.
If this is a documented issue with a fix then no worries. But if not and
anyone wants me to check into any further specifics, please let me know.

Note that the only directly mounted share is __active, mounted at /.
