Thanks.

Perhaps Konrad, Jan, Or Ian can tell whether the patch still needs to go
in stable as is, because the problem it fixes is more severe than the
problem it apparently creates. Maybe a mainline fix is needed before
this can go in, or perhaps even a stable specific fix (if context
changes are to blame).
