Does that mean that you didn't observe this with earlier
versions?

No, that shouldn't happen.

What I've noticed are these strange log messages:

Dec 29 22:55:07 vbox1 pengine: [28757]: notice: clone_rsc_colocation_rh: Cannot pair clvmd:1 with instance of cl-dlm

Even though all clones run on both nodes, there seems to be some
confusion. For instance:

Dec 29 22:55:00 vbox1 pengine: [28757]: info: find_clone: Internally renamed clvmd:0 on vbox1 to clvmd:2 (ORPHAN)
Dec 29 22:55:00 vbox1 pengine: [28757]: info: clone_rsc_order_lh: Inhibiting clvmd:2 from being active
Dec 29 22:55:00 vbox1 pengine: [28757]: notice: LogActions: Leave resource clvmd:0      (Started vbox2)

Does this reproduce from start or only after the cluster has been
running for a while?

Otherwise, this will have to wait for Andrew.

Thanks,

Dejan
