With the help of David, I managed to eventually have a coredump. First and foremost, if anyone has ssh access, on this box there is everything: ssh jenkins-slave-vm03.ovirt.org the box is a FC19 up-to-date as 20140508 cores are on /var/log/core the most up-to-date and recent coredump to use is core.6729.* I copied the xz-compressed coredumps, the output of `t a a bt full` and the package listing on the box here https://drive.google.com/#folders/0B9ZpeH8QzH5rY1NEZUpwZUw2bzQ

I'd like to use space on fedorapeople.org but in order to activate my space I got stuck here http://fedoraproject.org/wiki/Infrastructure/fedorapeople.org#Accessing_Y... -> You must be sponsored in a group (other than the CLA groups) and I used gdrive to speed up to process and to avoid wasting more time I'm investigating the dump and the backtrace as I write. Let me know if anyone has trouble downloading anything or if there is something more which needs to be uploaded.
