Bruno,
you need an account and must be logged in, then there is a button "Create Ticket" on the left side.
I assume, that you don't have an account on sourceforge.net, so I created the
ticket for you.
If you have more suggestions or bug reports, please consider if you want to register an account on sourceforge.net.
