[Paraview] Two leaks from vtkPVPluginLoader.cxx

[Takuya OSHIMA]

Hi,

This time I got two leaks from vtkPVPluginLoader.cxx. What is attached
below is the log from Apple's leaks tool. I guess the first one occurs
because the if-block at lines 97-100 prevents the allocated string to
be released when this->SetFileName(0) is called in the destructor. The
second one is because the string allocated by vtkSetStringMacro(Error)
is not released at the destruction of the object. Just guesses and not
confirmed, though.

Regards,
Takuya
