Subject: [PATCH] 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
