From what I can tell it is not just an Alt-Tab issue but involves moving away from the emacs window. For example this same bug will also cause firefox to lock up if you move from emacs22-gtk to firefox on another screen. No Alt-Tab involved. Taking focus away from emacs22-gtk releases firefox. I have seen this happen with other applications too.
At least on Intrepid, disabling Assistive Technologies only changes the bug behavior.
