Hi Laurent,


we identified and fixed the problem today - thanks to your
test case. Feel free to checkout our git sources [1].

The next latest stable snapshot will also reflect the
changes [2], but I'm not exactly sure when it will be released.
We might move this task up on our todo list ...


Regards,
Lukas
