This is still broken.
A simple "rbd map" works, but option parsing is busted:
$ sudo rbd map -o ro testimg
rbd: sysfs write failed
In some cases useful info is found in syslog - try "dmesg | tail".
rbd: map failed: (519) Unknown error 519
meaning errno = 519 from write()...
On one of the attempts it crashed in kfree(), probably called from
rbd_parse_monolithic().
Thanks,
