[xslt] Free deallocates an already deallocated object

[Manuel Barros <manuel enjazz com>]

Hi,

I am getting a runtime error under MacOS X in my debugger, which states 
that there are multiple frees on an already deallocated object.  I am 
wondering if this is related to the fact that xmlinit is being called 
several times.  This error does not occur under the Mac OS classic 
compilation.
