SVN commit 479280 by aseigo:

in kicker when we have items in the menu that use dirlister, they get
deleted at a point when the dirlister has had its holders removed so
calls to forgetDirs fail. so instead of using ASSERTS we just check for
the pointers instead of assert()ing them and voila! the kdirlister crash is gone! huzzah!
