[xslt] Crash in xsltproc

[Igor Zlatkovic <igor zlatkovic com>]

Hi there,

The following patch fixes a crash in xsltproc when the document passed first
on the command-line isn't a stylesheet.

Basically, the 'xsltParseStylesheetProcess(ret, doc)' returns NULL just few
lines above, and the code frees the stylesheet, setting the 'ret' pointer to
NULL. The next line of code references 'ret->errors', but 'ret' is now NULL
and the OS doesn't forgive the lapse :-)

I'll commit the patch shortly.

Ciao,
Igor
