 malloc() though it is not documented :(  Anyway it looks like you do not
 care about this case, so I'm ok to not do this check.

 impossible in this case, as we're adding two to the data length anyway.
 (Well, if that's -2 or something, I suppose, but that really shouldn't be
 happening.) malloc() returns NULL when it can't allocate memory. If you
 ask g_malloc() for memory, it asks malloc(). If malloc() returns NULL,
 g_malloc() calls abort() and the application terminates.

 Ok, I've removed this check.
