Meanwhile I was able to reproduce the behaviour. Many thanks for the detailed
analysis. It was very helpful. Could you please try the following additional
patch, in addition to the one from me you already applied and check if the
problem is now solved? The patch is against trunk, but it should work against
2.2.x without a problem.
