can't start pluto with Electric Fence enabled, on F30 with updates.

I noticed Electric Fence was disabled.
I enabled EF, then pluto, #master on F30, fails to start.
Tuomo suspect pk11-kit is part of issue.

Here are few lines from gdb bt, and link to full bt bellow.

gdb  stderr: there are bunch of gdb errors I not sure if they are related.  
warning: Loadable section ".note.gnu.property" outside of ELF segments

So far I have only noticed the crash on F30 with updates.
I wonder why this not happening in our kvm testing. May be the kvm install 
has a bit older pk1-kit* and/or NSS rpms. With an update this bug may appear 
in kvm testing too.

It is  triggered from call to NSS/NSPR, access freed memory and Electric 
Fence call abort.

Has anyone else noticed this issue with F30 updates or later?

there was a mention of p11-kit issue:
