Subject: [PATCH] imDefLkup: verify that a pointer isn't NULL before using it
It is possible for _XimICOfXICID() to return NULL, so it is necessary
to check this isn't actually the case before dereferencing the pointer.
All other callers of _XimICOfXICID() do this check too.
(The check itself is ugly, but it follows the style of the code in the
rest of the module.)
Fixes issue #45.
