This is a known bug. You have a couple of options, there
is a "quick fix" that you can use (see below). There is
also a "less quick fix" that involves a small hack to
the source code. The real fix is of course much harder.
I know how to fix it, but I just have not had time to
do it. Of course, if someone wants to volunteer to write
some code and regression tests, I would be glad to
explain how to implement the fix.
