[PATCH] Fix some memory leaks

[Claudiu Olteanu]

Yes, you are right. There is a simple white space fix in the
context of the memory leaks. I thought that since it is regarded
with the memory allocation/deallocation it wouldn't be a problem and
a second patch will be unnecessary. Sorry, my mistake.
I will create a new one when I will get home.

I also looked over the patch sent by Salvador and I believe
that there will be no problem if we will merge this two patches.
He doesn't use the freed variables and the ones implied are deallocated
before a return statement.
