Yep, fixed that for all flash actions (should be commited in the next
release). The flash module itself is pretty old and not well-maintained, and I
still hope that Macromedia will free the insane license that prevent me from
distributing the sources in an open project. (the flash module still can not
be included in Debian because of that, for example)
