Ok - can you please open a bugreport for the regression on the 4.9
branch so we don't miss the fix for the next 4.9 release which should
be in about 3 weeks from now (in fact you might miss the RC deadline
for that release).

So I suggest you commit the patch to trunk this week so others can
take care of backporting.

Thanks,
Richard.
