Aureport on Centos 7 : Strange behavior

Hi,
I came across a strange aureport behavior that would amount to a bug unless I am doing something wrong.
I am on Centos 7.2 with :
[root@odbfi021s ~]# rpm -qa|grep audit
audit-libs-2.4.1-5.el7.x86_64
audit-2.4.1-5.el7.x86_64

If I run aureport -k --summary -ts yesterday 09:00 -te yesterday 10:00 I get the answer immediately.

[root@odbfi021s ~]# aureport -k --summary -ts yesterday 09:00 -te yesterday 10:00

Key Summary Report
===========================
total  key
===========================
409  log_IAM
27  IAM64
26  audit_log
23  open64
16  etc
1deletion

Same thing with any round five minutes interval

[root@odbfi021s ~]# aureport -k --summary -ts yesterday 09:35 -te yesterday 09:40

Key Summary Report
===========================
total  key
===========================
1  IAM64
1  log_IAM

[root@odbfi021s ~]# aureport -k --summary -ts yesterday 09:40 -te yesterday 09:45

Key Summary Report
===========================
total  key
===========================
393  log_IAM
16  etc
11  audit_log
3  IAM64
2  open64
1  deletion

But If I request a ten minutes interval or a five minutes interval not starting at zero or five aureport hangs !

[root@odbfi021s ~]# aureport -k --summary -ts yesterday 09:35 -te yesterday 09:45

Key Summary Report

total  key

^C

Ausearch is ok with the same parameters :

[root@odbfi021s ~]# ausearch -ts yesterday 09:35 -te yesterday 09:45 |head

This is a known problem. It was fixed in 2.4.4.
