Patch for this problem.

For example, ioctx will be closed through xmlFreeParserInputBuffer (directly or indirectly) before the function is returned except xmlParserInputBufferCreateIO is failed.

Patch for this problem.

[Setting "patch" flag and correcting mime type so this can actually be queried for.]

Thanks Andre' for the triaging :-)

The intent of the patch is good but there is a problem in the sense
that it is legal to pass a NULL ioclose function. So I had to modify
the patch to take this into account to avoid a crash in that situation.
I commited the resulting patch:

http://git.gnome.org/browse/libxml2/commit/?id=24464be6390bc61a0f0e17890fbfc9c581434e29

 thanks a lot !
