Could be a duplicate of bug 901812.
Comment 11 Daniel Walsh 2013-03-06 17:43:34 UTC 
Yes it is the same problem.
Comment 12 Eric Paris 2013-03-06 17:50:31 UTC 
In /var/spool/abrt/ccpp-2013-02-24-09:29:21-848 there should be a core dump file.  Can you attach that file?  Can you also include rpm -qa libse\* \*policy\*   ?

Thanks!
Comment 13 Daniel Walsh 2013-03-06 19:05:57 UTC 
We have a potential race where we are writing the regex and an app attempts to read it, which this could happen.

libselinux-2.1.12-7.2.fc18  makes this atomic.
Comment 14 David Highley 2013-05-17 13:36:26 UTC 
Confirmed fixed with the above version.
