i know, the problem has been already fixed, but just for the record.

code like: if (bla) free(bla); will actually _never_ fix any bug.
either bla is a valid pointer and can be free'ed or bla is NULL and the
free does not hurt anyway, because one is explicitely allowed to free
NULL pointers by the standard.
