So, here are the files from both 1.4.4 and 1.5.0 versions:

(taken from same router the previous output was from)
http://tech.hq.norma.perm.ru/files/ospf-state-all-1.4.4.txt
(taken from another router)
http://tech.hq.norma.perm.ru/files/ospf-state-1.5.0.txt
http://tech.hq.norma.perm.ru/files/ospf-state-all-1.5.0.txt

I've also noticed that this prefix is missing from 'show ospf state'
output files, but present in 'show ospf state all' output files, but
along with a IP address of 172.16.5.159. This is an IP address of a
router this prefix is originating from (it's an address of it's tunnel
most close to the area 0), and it's not directly reachable from the
routers which FIB is missing it, so I suppose this may be the reason. I
have also noticed that other nssa areas have similar problem (they are
present in 'show ospf state all' output with IP address of their
originating router, and missing in FIB), on both 1.4.4 and 1.5.0 bird
versions.

Thanks.
