This happens for me, too: on a brand new installation of Intrepid (not an upgrade from hardy, or over a previous install). I've applied all pending package updates. The account I'm using has no individual emacs config files, and there is no local site config yet.
After reading the above comment about the strace indicating that emacs was running OK, I tried switching off compiz (ie, switching to "none" in the "Visual effects" tab of the appearance preferences). Suddenly all my latent emacs sessions became visible. And I can start new emacs sessions in this state. Switching compiz back on again does not hide any of the emacs sessions currently running; however, new sessions are not visible until compiz is switched off again. So, perhaps this is related to the video drivers in use.
