xlog min recovery request is past current point -- is it real problem?

Hello, All!

I get this messages from new standby:
2014-09-06 00:30:05 MSK pid=36409,user=,db=,host= LOG:  restored log file "0000000A0001213C000000B1" from archive
2014-09-06 00:30:05 MSK pid=36447,user=,db=,host= WARNING:  xlog min recovery request 12149/A5149BA0 is past current
point1213C/B1625590

Is my data broken and I will get wrong query results or it just some
warning without any problem for data?

PS:
PostgreSQL 9.2.6 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit
I promote standby to master, get backup from it and start new standby
from this backup. After all I get 43 messages like this in new standby log.
