+fix a memory leak in XRegisterIMInstantiateCallback
+
+Analysis:
+
+    _XimRegisterIMInstantiateCallback() opens an XIM and closes it using
+    the internal function pointers, but the internal close function does
+    not free the pointer to the XIM (this would be done in XCloseIM()).

+    Subject: Re: Yet another leak in Xlib
+
+    For reference, here's how I'm calling XRegisterIMInstantiateCallback:
+
+    XSetLocaleModifiers ("");
+    XRegisterIMInstantiateCallback (compositor.display,
+                                    XrmGetDatabase (compositor.display),
+                                    (char *) compositor.resource_name,
+                                    (char *) compositor.app_name,
+                                    IMInstantiateCallback, NULL);
+    and XMODIFIERS is:
+
+        @im=ibus
