This is the samefix as the 2.4 patch. I do not have a machine on which I
can test 2.6, but visual examination of the files suggested the same
mechanism. In fact, I was surprised that the 2.4 patch wouldn't patch 2.6
so I made this one.
It was made with 2.6.0-test1, and compiles.
Can someone confirm that 2.6 has the same bug, and that this patch fixes
it? I suspect it has, and suspect this fixes it, but can't test for lack
of an available machine.
Regards,
Bas Bloemsaat
