Hi Thomas,
Don't know for sure, i haven't seen it before, but on the other hand after a
reboot it is running fine now for some time.
So it seems it's not reliably reproducible :(.
OVS version is current Debian wheezy:
ii openvswitch-common
1.4.2+git20120612-9.1~deb7u1 amd64
Open vSwitch common components
ii openvswitch-controller
1.4.2+git20120612-9.1~deb7u1 amd64
Open vSwitch controller implementation
ii openvswitch-pki
1.4.2+git20120612-9.1~deb7u1 all
Open vSwitch public key infrastructure dependency package
ii openvswitch-switch
1.4.2+git20120612-9.1~deb7u1 amd64
Open vSwitch switch implementations
