What I find very strange is that there are multiple threads that execute the same line (or perhaps I do not interpret the gdb output correctly).

Can I get access to such a slave to debug this?

We still have no guess regarding what made this pop up. I can confirm that this happens quite often, on different slaves. E.g
http://jenkins.ovirt.org/job/vdsm_master_check-patch-el7-x86_64/22648/console
where the command

'/usr/bin/ovs-vsctl', '--oneline', '--format=json', '--', 'add-br', 'vdsmbr_test', '--', 'list', 'Bridge'

gets stuck.
