I just experienced this bug (Emerald crashing in combination with Window-applets, set to hide decorations for maximized windows) and decided to play around a little. My relevant setup is:
I disabled the setting in Window Applets to hide decorations for maximized windows, went to Compiz Settings Manager and set "!state=maxvert" for window decorations. This solved Emerald crashing. Things now work as expected: On maximize, decorations are removed and the window can be controlled via Window Applets. On restore, Emerald decorations return - without any crashes.
Setting the Window Applets key to remove decorations on maximized windows again makes Emerald crash once more. This behaviour is reproduceable.
