This happens to me too, not only with skype chat windows but any chat window type.
When I close the last tab on a window chat (i.e. the whole window) with Kopete window minimized on the tray icon, the window is closed by I can't restore kopete window just clicking on the tray icon. As Bernie says I have to open it from the applications menu or with shorcut (ctrl + shift + s) and then quit due to its weird state.
